It's far from a secret that the air filter has some effect on power. power unit vehicle and its efficiency. The more effective its filtering properties, the more it dampens the engine. In this case, a compromise is necessary: ​​the installation of an effective filter element with less resistance. Does such a filter exist?

What is a zero resistance filter for?

There is an opinion that such a filter is a filter with zero resistance. Even despite the good performance indicators filter elements of this design, yet the attitude to their installation cannot be called unambiguous. Many motorists note the fact that after changing the usual element to a filter with zero resistance, no changes were noticed.

Figure 1. Zero Resistance Cone Air Filter

On one of the sites I came across an article, it is given below, which talks about all the advantages of such filters and claims their usefulness.

What does the use of a zero resistance filter give

The purpose of air filters is to prevent the ingress of various particles into the working area of ​​the cylinder-piston group of the engine.

Greater airflow filtration efficiency inevitably leads to losses in engine power. Standard paper filters manufactured by Bosch, Mann, Champion, Fram, SCT or Hengst are characterized by significant resistance to airflow due to the fact that the density of the filter material is very high. The stronger the resistance, the greater and more noticeable the loss of power. This is especially evident before the filter replacement period, when it is already quite dirty.

The design of the filter with zero resistance provides the ability to reduce the resistance to inlet flow without compromising the filtering properties and loss of motor power. Zero-resistance filters have become widespread among sports cars, when it is important to add a few drops to the engine. Horse power.

At the heart of the “nulevik” filter element is the use of multilayer cotton gauze impregnated with a special oil composition, which is located between pressed aluminum screens.

The standard air filter has the ability to clean the air flow with only one plane. The design of the nuleviks allows for the process of filtering the incoming air with the entire surface, which contributes to the retention of more dust. Filter impregnation zero resistance causes dust particles to settle sequentially on each layer of cotton fibers.

The resource of standard air filters is very limited and averages about 15 thousand kilometers, after which they must be replaced. Cleaning this filter does not bring the desired effect. But filters with zero resistance have a resource exceeding 100 thousand kilometers.

The economic effect observed after installing a filter with zero resistance:

• the advantage, first of all, is that its installation allows you to save fuel up to 4%, due to the powerful air flow and increased filtration effect;
• there is also an increase in power up to 5%, while maintaining the filtering ability compared to a standard element; a more complex element design provides low resistance to air flow and has significant filtering properties, which protects fuel system from pollution and piston group from premature wear.

Many people like the appearance of a unique inductive noise coming from the filter when the engine is running.

The owners of some SUVs quite positively characterize the installation of a “nulevik” on a car. And if we take into account the frequent movement of such cars off-road, then the use of this filter is accompanied by a quick payback.

If you are the owner of a fairly new car that has completed chip tuning and refinement of the exhaust system, then installing a filter with zero resistance will be quite effective.

As for old cars or low power ones, such as the classic model line VAZ, then the purchase and installation of a filter with zero resistance will in no way affect the increase in power or improve efficiency. Such a replacement is not justified and looks like nothing more than a farce of the owner.

It should be noted that the purchase and installation of a low-quality filter will not only not improve the performance of the motor, but can also greatly harm it, since such elements filter even worse than standard filters.

It should be noted that a filter with a conical design is able to add a little more performance to the motor than a filter installed in a regular place.

Opinion on the inefficiency of nulls

In order not to tire you much with reading, I will not describe the disadvantages of a zero-resistance filter. I think that it will be much more interesting to watch a video test, the conclusion of which is based not on speculation and subjective opinions, but on real measurements taken by a special device. So, let's look.

To believe in the uselessness of the filters we are discussing or not is up to you. However, my opinion is that if such filters were more effective than paper or fluff filters, then car manufacturers would install them regularly, off the assembly line. In general, I am against the installation of filters with zero resistance.

Installing a zero resistance filter on a car

If, after watching the video, you still want to test the effectiveness of zero-resistance filters from your own experience, then proceed as follows. First, dismantle the filter housing itself. Then remove the section with the sensor mass flow air. After that, the filter with zero resistance is attached with clamps to the section with the mass air flow sensor, and the entire structure is attached to the air intake pipe.

The filter must be carefully secured to prevent it from dangling.

Special kits are available for sale, both for mounting the filter on any car, and for installation on a specific model.

How to maintain a zero resistance filter

Filter cleaning, as well as installation, can also be carried out with my own hands. The filter is dismantled and, using a brush with a soft fluffy coating, gently clean the outer surface of dirt.

Then apply Universal Cleaner to all sides of the filter. After 10 minutes after the complete impregnation of the filter element with the composition, the filter should be washed with water in a container, and then washed again under running water.

Figure 3. Zero resistance filter cleaner

It is not necessary to dry such a filter, it is enough to shake it strongly a small number of times to remove residual water. Drying with heating devices is not recommended, so as not to damage the filter element. If white spots appear on the outer or inner surface of the filter, it can be re-impregnated. After that, the filter is installed in its place.

If you drive a car frequently in very dusty conditions, the oil for the zero resistance filter is reapplied every five thousand km. Under normal operating conditions, impregnation is carried out after 10 thousand kilometers. The filter resource is able to withstand at least 20 washes.

Many car owners, wanting to improve the power and dynamic characteristics car, they decide to put a filter of zero resistance. It is difficult for an uninitiated person to judge how justified such a step is. Among motorists, there are directly opposite opinions regarding such a car upgrade. Some are sure that the installation of a "zero" allows you to significantly increase the power of the engine, "strangled" by a regular air filter, and therefore, it is not only necessary, but vital. Others argue that one filter of zero resistance for boosting the power unit is not enough, therefore, there is no point in it, besides, there is a prejudice that such a device copes much worse with its main task - cleaning the air entering the engine.

As usual, the truth lies somewhere in the middle, but first things first.

What is a zero resistance filter?

Atmospheric air contains many mechanical impurities, primarily dust, which, once inside the engine, can sooner or later disable it. To prevent a premature end, this air must be purified. To do this, you need an air filter, which carries out mechanical cleaning.

The power of the motor directly depends on the amount of air involved in the preparation of the working mixture. The better the air is filtered, the less it enters the engine, and the more power drops. Regular filters are made of a fairly dense material that provides great resistance to flow. As it gets dirty, the resistance increases even more. This becomes especially noticeable during dynamic driving - the car becomes "dull".

The Zero Resistance Air Filter is designed to provide minimal intake resistance without compromising cleaning performance. It is for this reason that it is mandatory installed on racing cars.

Its filter element consists of several layers of cotton fabric impregnated with a special agent and placed between an aluminum screen. It allows the air flow to pass almost unhindered into the motor. Dirt particles from the passing air flow stick to the fibers, practically without reducing the throughput of the filter.

Zero resistance filter maintenance

In order for the filter to do its job well, the car owner must service it regularly. The procedure is not particularly difficult, but it takes time.

• First, the filter must be removed and cleaned of dust with a soft brush. Thus, large particles of dirt are removed.
• After that, the filter must be treated with a special cleaning agent and wait 10 minutes until the entire filter element is saturated.
• Then the filter must be washed first in a container with water, and then under a weak pressure of running water. After rinsing, shake off any remaining water.
• Do not dry the filter with heating elements, as this may damage it.
• The dried filter should be carefully inspected. If light spots remain on its surface, the impregnation will have to be repeated.
• Finally, the dried filter can be put back.

The expediency of installing zero

However, one should not be deceived by the sharply increased dynamic characteristics of the machine, because the increase in power will be only 5-6 percent. Even a calculator is not required to calculate that, for example, in a Lada Priora car, installing a zero-resistance filter gives an additional 5 hp.

In practice, a person is not able to feel such an increase in power, therefore, such a procedure will only allow to amuse pride with the realization that Engine efficiency got a little better. The zero-resistance filter will also not have any serious effect on the dynamic characteristics of a conventional car. Therefore, it only makes sense to put it in order full tuning engine, then its advantages can be fully manifested.

We must not forget about the disadvantages of such a filter. He demands regular maintenance, and the price of a high-quality zero-resistance filter is several times higher than usual, and may cast doubt on all its advantages.

Or maybe no filter at all?

There is a misconception among motorists that if the filter is completely dismantled along with the housing, engine power will increase significantly. In fact, this is absolutely not the case; dismantling does not give any gain. The reason is that when developing a power unit, engineers initially calculate the valve timing, taking into account air filtration losses. In addition, in uncleaned air, the motor will not last long, because. abrasive particles will quickly do their job.

Do-it-yourself alternative or "nulevik"

Some car owners, not wanting to spend a lot of money on buying an expensive branded zero-resistance filter, prefer to make them with their own hands. As a donor, a regular round filter from Moskvich of any model is most often used. With the help of glue, sealant, a clerical knife and a round box from CDs, it is converted into the so-called "nulevik". What for? Everything is very simple. main reason, pushing car owners to make a filter with their own hands - the issue price, which does not exceed 150 rubles.

Needless to say, such a self-made "nulevik" remains the same "Moskvich" filter, and its characteristics will not get better. In addition, we should not forget that in the 70s the technology was not as perfect as it is today, and motors made forty years ago were not as demanding on the quality of air purification. Therefore, the filters that were installed on these engines are capable of retaining only relatively large particles. The conclusion is simple: installing a do-it-yourself zero-resistance filter on modern cars is not allowed. Otherwise, there is every chance to ruin your iron horse.

Perhaps, the only car, in which you can install a home-made "nulevik" in order to achieve some kind of effect - this is the same "Moskvich". Some owners cut off the walls of the case in which it is placed. Thus, an unnecessary obstacle in the path of the air flow is eliminated.

The zero resistance filter is a detail that adds to the car engine when tuning. These elements are quite accessible to the consumer and are easily installed in the motor. They come in a variety of designs and look great too. Studying all the pros and cons of a zero resistance filter, you can decide on the need to install it on a car engine.

If you want to add a few "horses", then know that almost every process of refinement and tuning of the engine does not pass without a trace. And in the general plan of the totality of processes, this is a noticeable increase in power indicators. Any engine tuning is not complete without improvements to the air supply system, on which the efficiency of the motor depends. The zero resistance filter, reviews of which are mostly positive, due to its excellent ability to pass air, affects the formation of the fuel-air mixture.

Purpose

Simply put, the main function of any air filter is to remove various unwanted impurities. This element must protect the piston group and cylinders from possible ingress of dust and moisture into them.

At the same time, having good car loses its power. Due to the dense paper, the flow of consumed air encounters serious resistance and passes through the filter worse. Therefore, with high resistance, the power of the power unit is also lost. And at the moment when it becomes clogged, the fact of the loss of power indicators is especially noticeable. The zero filter has a certain design that contributes to high-quality air purification, but at the same time significantly reduces the air flow resistance at the inlet, which, in turn, contributes to an increase in power. As a rule, the installation of a zero resistance filter occurs on all sports and racing cars to add some extra horsepower to their motors. Considering that this element of engine equipment can be easily purchased at auto parts stores, many motorists install zero filters on the engines of their cars.

Keeping it in good condition

Like any other element, this filter needs to be cleaned. To do this, it must be dismantled and, using a special brush, carefully clean all surfaces of the element. Next, you need to apply a special cleanser to the surface of the filter and hold for ten minutes until it is completely absorbed. After that, the filter element should be washed and rinsed under running water.

When operating a car in normal climatic conditions, flushing is recommended every ten thousand car mileage. When using transport in less favorable conditions, cleaning is carried out every five thousand. After flushing about twenty times, the element should be replaced with a new one, since the working resource is completely exhausted.

Advantages of the zero resistance filter

Increasing the amount of air supply passing through it provides power plant plenty of oxygen needed for normal combustion fuel mixture which ultimately increases power.

It should be noted that by installing a zero-resistance filter on a VAZ, one should not expect a decent increase in power. On engines with a small displacement, the increase in power indicators is almost imperceptible, unless, of course, we consider diagnostic indicators in digital equivalent on special stands. And, for example, on units with a volume of 3 or more liters, the factor of increasing dynamic performance is quite noticeable, it is on such engines that all the positive qualities and advantages of such an air purification element are revealed.

Second positive quality filter can be called a change in the sound of the engine coming from under the hood. Due to the design features of the nulevik, a sound characteristic of sports cars is heard.

Changes and appearance engine. Some motorists install such an element precisely because of the aesthetic appearance and aggressive sound.

disadvantages

The disadvantages of a zero-resistance filter are minor, but they still exist. Firstly, it is the need for constant care of the condition of the filter element. Second negative factor can be called poor-quality air purification from impurities. Often this can happen if the element is inexpensive and of lower quality than expensive counterparts.

Pros and cons of a zero resistance filter at a VAZ

One of simple ways car tuning VAZ models is to install a zero filter on the engine. At the same time, the price of the issue is not very high, and the installation can be done independently. You can mount a VAZ-2110 zero resistance filter on the motor as follows. First you need to disconnect the rubber pipe from This can be done using a regular screwdriver. Next, you need to dismantle the sensor mount from the standard air filter housing and remove the element itself. Then you need to disconnect the negative wires from the cylinder head. We fasten the mounting bracket to the engine housing. We fix the air sensor mounting bolts to the filter mounting bracket. We install the sensor on the part, and finally connect the air sensor connector. How does it look in engine compartment zero resistance filter?

Photos indicate that this device fits perfectly into the overall appearance of the power unit and gives it a certain aggressive character.

K&N filter

Products of this manufacturer are firmly established in automotive market and have a huge number of their admirers.

The K&N zero resistance filter was developed in California by the company of the same name to help increase power ratings. According to their characteristics, the products of this manufacturer are in many respects ahead of their counterparts of competitive firms. According to the developers, its installation on the engine will increase the power output by as much as four "horses". The element can be used for a long time, and when operating a car in ordinary urban conditions, it can be cleaned only after 80 thousand km of the car run.

K&N is made from the purest cotton.

The main parts of the element consist of several layers of cotton, which are located between two aluminum plates. To improve the performance of the filter, it is impregnated special oil, And his design features provide durable and reliable performance on any engine.

All products from this manufacturer are guarantee period service, which, according to the company's engineers, is one million miles.

Kinds

There are two types of zero filters, which differ in geometric shape and installation method. The first are cone-shaped. This type of filter is very effective, as it is located under the hood without an additional protective cover. Also, its advantages increase with the use of smooth pipes with a minimum number of bends, in contrast to corrugated ones. The second - elements installed in a regular seat.

Installation

How to properly mount a zero resistance filter? Reviews of motorists say that for this it is desirable to choose the “coldest” place under the hood of the car. This is to ensure that the incoming air is as cold as possible.

It is undesirable to place the filter near the radiator and manifold exhaust gases, because of this, the efficiency is significantly reduced.

To protect the element from possible contact with it engine oil it is recommended to install a protective cover on it.

What is the result?

Having considered the pros and cons of a zero resistance filter, the car owner will decide on the installation of this element. If, nevertheless, you decide to equip the engine of your "iron" friend with a filter of this design, then the selection and installation of the null should be carried out with the correct approach to this procedure, so as not to damage the state of the power unit. Professional racing cars are equipped with this product as standard, because on their powerful motors its action is very noticeable. When driving a car at high speed, the air flow creates a swirl in the intake tract, almost turning into a small hurricane. Due to this factor, a vacuum moment is created in the system, which the zero filter does an excellent job of straightening the air flow.

At the same time, the probability of dust getting into the engine cylinders is very high. For racing cars, this is not essential, since after almost every competition their engines are repaired and the piston group is replaced.

Conclusion

The pros and cons of a zero resistance filter depend on the quality of workmanship and the materials used in their manufacture, on the type of the product itself and the car engine. Therefore, the final decision on the installation depends only on you.

Almost all motorists have a desire to increase the power and dynamics of their car. At the same time, everyone uses their own methods, based on their capabilities and level of knowledge.

Some optimize the engine, others install various body kits and spoilers, others use high-quality “consumables”, and so on.

But experienced car owners know about another popular method - installing a zero resistance filter.

So what is this device? What are the differences between "nulevik" and standard filters? Does it make sense to spend money? Let's figure it out.

What is a zero resistance filter for and where is it used?

The task of the air filter installed in each car is to clean the flows entering the engine from various “garbage”. But here the “stick” is at two ends.

On the one hand, installing a filter allows you to clean the air, and on the other hand, it creates additional resistance to the flow.

The result is a decrease in power, which is especially noticeable as the filter element gets dirty.

Zero resistance filter is an alternative to the classic filter. The main purpose is to reduce the overall air resistance without compromising the quality of cleaning.

It is believed that the installation of such a filter allows you to achieve an increase in engine power by an average of 5-7%. At the same time, it is almost impossible to feel the difference from the installation. There are only facts to be believed.

Nuleviki are actively used on sports cars for the same purpose - to add power to the power unit. At the same time, any alternatives are not even considered.

But it should be noted that the difference sports cars not only in the installation of a special filter, but also in a more advanced exhaust system that allows the release of large volumes of exhaust gases even at maximum speed.

How is it different from other types of filters?

The main difference between the "nulevik" lies in its design. Classic filters installed on most cars are made of paper (more precisely, from compressed fibers).

The flow of air masses passes through small holes in the fibers, and then goes to the motor.

As soon as the fibers become clogged, the resistance also increases, because the air needs to find new ways to overcome the obstacle. If nothing is done, then the engine power drops.

Based on current standards, the filter paper should be thicker with maximum fiber compaction. With this design, high-quality cleaning is ensured, but the resistance is already too high immediately after installation.

The design of the "nulevik" is based on the principle of resistance reduction.

At the heart of the device are several layers of cotton, which effectively trap dust and dirt. In this case, the retained particles, in fact, become part of the product.

Due to this, the efficiency of the filter element is higher and one square centimeter of surface receives more dust than its predecessor.

The cotton cloth is sandwiched in an aluminum screen, which increases the filtering surface. The developers claim that the working part of the “nulevik” is 4-5 times larger than in the classic filter, which ensures a long service life and less resistance of the product.

This is achieved due to another factor - the presence of a special coating (oil) on the cotton, which traps dirt without harming the flow.

The principle of the filter, its features

The principle of operation of the "nulevik" is based on two factors:

• high-quality cleaning of the flow entering the motor;
• minimum air resistance.

The effectiveness of the zero resistance filter is due to the unique design and the use of cotton (rather than paper) material.

The incoming stream is filtered from dust without much contamination for the product. Thanks to a special impregnation, particles entering through the filter settle on the surface and do not interfere with the flow of air to the combustion chamber.

As a result, a sufficient amount of air enters the intake manifold, and the power of the power unit increases.

Advantages and disadvantages of "zero"

As practice shows, such filters have their positive and negative qualities.

Let's start with the pros:

• increase in power by 5-7%. Of course, this may not be noticeable to the driver, but when installed in combination with other types, the result can be felt for yourself;
• change in the sound characteristics of the motor. It is believed that the filter element makes a special sound, which changes the overall hum from engine compartment. Many motorists install "zeros" for this very reason;
• the appearance of the space under the hood changes - it becomes more sporty.

Cons of "zero":

• the need for constant care, which not all car owners like to do;
• Affordable filters are of poor quality, so they clog almost immediately. The oil also gets dirty faster, which leads to a decrease in the resource of the power unit.

How to take care of these filters?

As already mentioned, one of the main disadvantages of the filter is the need for regular maintenance.

After purchasing and installing the product, it must be washed and processed regularly. At the same time, processing according to the principle “removed-washed-installed” will no longer work - a special algorithm is required here.

The frequency of flushing is every 5-6 thousand kilometers. If the car is operated in areas with high dust content or off-road, then it is necessary to clean the filter more often.

If you forget about servicing the device, then the car becomes “gluttonous” and “dumb”.

The algorithm of actions is as follows:

There are even special kits for caring for “nullers”, which include washing and impregnation. A few manipulations that are described above, and the product looks like new.

Please note that the total number of washes may be limited to around 20. After that, install new filter.

Installation Features

Many motorists make a big mistake - they incorrectly set the "zero" because of which he is not able to perform his functions normally.

For example, the filter is installed too close to a hot engine or exhaust manifold. Here it is time to remember physics.

The density of cold air is higher than that of hot air. As a result, cold air is easier to "shove" into the combustion chamber than hot air.

Therefore, the “nulevik” should be located as far as possible from any heat sources (motor, exhaust manifold, etc.).

In addition, a dirty filter will have to be “repaired”, which will also take some time.

Today there are many models of zero filters that are designed for mounting on various types of cars - with an injector or a carburetor.

The material can be mesh, foam rubber or cotton. Foam rubber filters have the highest degree of purification, but they also have more resistance than their “brothers”.

Installation of "nulevik" on different cars produced in different ways, but in general, you need to follow the following algorithm:

• discard the connector from the DMRV (mass fuel flow sensor);
• use a screwdriver to disconnect the rubber tube from the MAF;
• remove the sensor fasteners from the housing (for this you will have to unscrew a couple of bolts);
• dismantle the case and remove the rubber clips (use platypuses or pliers);
• unscrew the mount from the group of wires;
• fasten a couple of bolts from the DMRV retainer to the “nulevik” fastener;
• put a new filter on the DMRV, stretch the clamping clamp and connect the sensor.

That's all, the new filter is installed on the car.

How to make a zero filter with your own hands?

Some motorists, in the desire to save money, decide to make a “nulevik” with their own hands.

As a source, a factory round filter is used, which was once mounted on Moskvich cars.

To make a "zero" you can use different ways. We will describe one of them below.

You will need improvised tools (foam rubber, sealant, sharp knife, glue, and others). Total price question - no more than 3-4 US dollars.

It should be noted right away that the converted “nulevik” is unlikely to add power to your car. The reason is outdated technologies that were used in the production of cars in the 70s and 80s.

When creating filters, manufacturers thought little about the importance of cleaning, so old products only trap very large pieces of dirt. So, by "creating" a zero filter, you are taking a certain risk and can "kill" your engine.

By the way, the only car where such a zero filter will have to “go to court” is Moskvich. At the same time, there are owners who immediately cut the walls to eliminate excess flow resistance.

If you still decide to experiment, then the sequence will be as follows:

• remove the standard device;
• from a piece of plywood, make a rectangular adapter with a hole.

Drill four more holes and fix the adapter to the air meter sensor.

Before that, install a piece of pipe in the hole and seal the cracks with sealant;

• make additional holes in two circles of plywood. At the same time, on the outer circle, make a hole of a larger diameter, and on the inner one (installed near the air meter) - according to the diameter of the pipe being installed. The latter shrinks with a sealant;
• make 3 bars with a length of about 16-18 centimeters and use them to fasten the circles. The result is a kind of cylindrical figure. Since there is no plywood in the bars, it is necessary to make holes around the edges for mounting self-tapping screws (otherwise the plywood may be damaged);
• to prevent foam rubber from falling out, make a case. For its manufacture, you can take a mesh for GVL joints. The advantage is the presence of a sticky base, which will allow you to immediately fix it;
• after that, foam rubber is glued from the outside with the help of a thermosealant, which allows you to securely and quickly fix the device;
• fix with a sealant a couple of pieces of foam rubber for the side of the barrel;
• put on foam rubber and fasten the plywood bars with ties.

There are also simpler solutions.

From the beginning of the engine age internal combustion engineers were preoccupied with the invention of a device that would purify the air entering the engine.

Over the years, filters have become simpler, smaller and more efficient, and not so long ago, the modern zero-resistance filter appeared on the market, which can be found in most sports and racing cars today.

According to the principle of air filtration, it is closer not to simple paper ones, but to oil-based devices that are already outdated today, which were operated in difficult conditions. In them, air passes through a conditional "curtain", which constantly rotates and dips into the oil.

The oil traps large contaminants, and the fabric mesh is lighter. Modern nuleviki, of course, have little in common with oil filters, but the principle of delaying pollution due to the oil base has been preserved.

It should be understood that if you decide to install Nulevik filter, you need to take care of upgrading and other devices in the iron horse.

When tuning the engine, motorists neglect to change the intake system. And this is necessary, since with an increase in power, more air is required, which means that you cannot do without filter-zero resistance. It is also recommended to set an increased throttle valve, sports camshafts, and bore the cylinders.

Let us consider in more detail the device of nuleviks, their features, service rules.

Zero resistance filter installation

What is a zero resistance filter - design

Nulevik has a more complex design compared to a simple air filter, which gives it a number of advantages. One of the most important design elements is a multi-layer cotton filter fabric, we will describe what it is for and how it is installed.

1. Cotton paper with densely pressed fibers is used as a filter material. Dirt getting into the structure, clings to the fibers and turns into part of the filter element. Due to this, the zero resistance filter filters out much more dust per square inch than paper counterparts. In some models, you can find foam rubber matter. At the same time, the smaller the pores in the filter material, the more efficient the operation of the device.
2. The filter cloth is placed in an aluminum screen. Such zero resistance filter housingincreases the surface usable area by five times and makes it possible to pass more air, while dirt practically does not interfere with the passage of air flow.
3. And of course, the correct impregnation of the element is not unimportant. special composition oils.

VIDEO REVIEW

What does a zero resistance filter give - is it worth it

A conventional air filter is designed to clean the air, namely from the penetration of dust and other contaminants from the outside into the engine. But a side effect of air cleaning is a reduction in engine power, since the paper material has a high resistance to air flow. The thicker the paper, the higher the resistance, and hence the higher the power loss of the engine.

The zero resistance filter makes it possible to solve this problem due to a slightly different device. It is used instead of conventional air filters to reduce engine power losses, while the quality of air purification remains high.

Of course, it is more effective in specially prepared and racing cars, since in cars with conventional engine, installing a filter gives only an increase of 3-5% of power, and the driver simply may not feel any difference in the acceleration of the car, and the cost of installing expensive equipment will turn out to be useless.

So let's sum up the pros and cons:

Pros:

• effective air purification while maintaining engine power due to a complex filter configuration,
• reusable use - every 15 thousand kilometers it is recommended to clean it from contaminants, rinse with water and treat with a special agent,
• increase in engine power - after installation, engine power is increased by five percent, plus a unique noise characteristic of sports cars appears,
• ease of installation (installation is possible without the involvement of a car mechanic),
• a large selection of models from different manufacturers.

Minuses:

• the need for regular care, the purchase of a special treatment solution,
• rather high price for quality products.

Thus, the use of zero is really necessary and justified if the car is equipped with a forced engine, or you are planning to tune your car.

Maintenance of Zero Resistance Filters

After the purchase, you should immediately take care of purchasing a special solution for impregnation. The use of this tool is mandatory, otherwise the filter will quickly become clogged and cease to perform its functions.

VIDEO REVIEW

Device care is performed according to the following algorithm:

1. remove the device
2. remove dirt with a brush with soft bristles,
3. Apply solution to both sides cleaningzero filter resistance and leave it for a few minutes
4. rinse in a container of water, then rinse under running water and shake well,
5. put back in the car.

It is recommended to repeat the washing and processing procedure every 8-10 thousand kilometers, with intensive use - every 6-8 thousand kilometers. One filter can be treated in this way up to 20 times on average, after which it must be replaced with a new one.

What not to do!

Moisture does not need to be dried completely, and even more so, heating elements, such as a heater or a hair dryer, should not be used.

Is it worth installing a zero filter on a motorcycle or scooter

Zero filters are often installed by owners of two-wheeled vehicles - mopeds, scooters, motorcycles. In particular, this applies to sports vehicles with a powerful engine.

The selection of a zero for a scooter or motorcycle is carried out taking into account the diameter of the inlet pipes. For scooters with a volume of 125-150 cc and a G6 engine, this figure is 42 mm, with a volume of 50-100 cc - 38 mm. Similarly, the selection of a device for a moped is performed.

Purchase zero resistance sports filter for motorcycles and scooters is justified if complex tuning is planned. The factory intake and exhaust systems are designed for a certain air flow, so when changing the filter, additional adjustments to the exhaust system and carburetor will be required. If you do not carry out these works, then most likely you will encounter premature wear all parts of the system and early engine wear.
