Almost every motorist has heard of the existence of an alternative to regular air filters, which provides an increase in engine power without any modifications. This is a zero resistance filter. Adding a couple of horses, while replacing only one element, is a tempting prospect. However, as you know, in practice there may be some difficulties. Therefore, an ordinary driver often cannot answer the question of whether it is worth putting such a part on a car, there are too many controversial points.

In order to dispel all the myths about the so-called "nuleviks" and give an unambiguous answer, we will consider the design, principle of operation, varieties, maintenance requirements, advantages and disadvantages of such products, and then summarize.

Zero resistance air filter device and its principle of operation

As you know, for the normal operation of the engine internal combustion, whether diesel, gas or gasoline, it is necessary that the cylinders through the intake valves receive fuel-air mixture in the required proportion. To do this, the engine takes air from the atmosphere. But, atmospheric air is not clean, along with it, grains of dust, dust particles and other foreign objects can get into the combustion chambers, which can cause significant harm, significantly reducing the life of the engine. To prevent this from happening, the intake air is first passed through an air filter. Standard factory filters provide an insurmountable barrier to dust, but have significant inlet resistance as air passes through dense cellulose layers. In addition, over time, the micropores of a standard element become clogged with dust and the filling of the cylinders with air worsens even more. Such resistance has an extremely negative effect on the operation of the engine, reducing its power.

An air filter of zero resistance does not have such a disadvantage, since it practically does not impede the movement of the flow, providing maximum possible consumption air in the channel, thereby allowing the motor to operate at the required mode without interruption. The work of the "nulevik" is especially noticeable on high speed when it is required to supply significant volumes of air, while regular filter elements, due to the features described above, cannot cope with such a task.

The design of low-resistance filters is quite complicated, since they must not only not interfere with the movement of air, but also have time to fulfill their main task of cleaning it. Most often, such elements are made either from cotton canvas or from synthetic materials. Moreover, they try to make the number of layers minimal in order to achieve the lowest possible resistance at the input.

Zero resistance filter installation

You can put a “zero” on any car, since not only “zero” filters are currently produced that are mounted in regular places on specific car models, but also universal products that can be installed using a special adapter that comes most often in the kit on the different types engines regardless of the design of the standard mount.

You can perform the installation yourself, without the involvement of service station workers. The procedure is extremely simple and takes only a few minutes. All you need to do is remove the standard filter element and install a new one. In the case when a universal filter is installed, it is additionally necessary to dismantle the factory housing, which will also not create any problems.

It should be noted that during installation it is very important to ensure the tightness of the pipes in order to completely exclude the possibility of dirty air entering the engine tract. Also Special attention should be given to the location of the filter. If a conical sports filter with a flexible pipe is installed, then it must be fixed as far as possible from the radiator so as not to spoil the parameters of the inlet air.

Pros and cons of "zeros"

Summing up the above, we emphasize the main pros and cons of zero-resistance air filters.

The advantages of such tuning parts include:

• low input resistance, allowing to increase the power of the internal combustion engine;
• easy installation and dismantling;
• compactness, "nulevik" takes up much less space in the engine compartment;
• a significantly longer service life compared to standard products;

However, in addition to the advantages, there are some disadvantages:

• the need for regular maintenance"nulevik", as well as the need to purchase additional impregnations;
• higher price of the product;

Types of zero resistance filters

Before dwelling in more detail on the maintenance of low-resistance air filters, it should be noted that all "null" can be divided into two groups:

• "dry", those that do not need additional impregnation with special substances;
• “wet” filters that need to be regularly treated with a sticky substance that traps even the smallest pollen;

"Wet" filters have a higher filtering capacity, but they are more expensive and require more attention than their "colleagues". It is they who are recommended to be installed on motors with film sensors. mass flow air that does not tolerate pollution.

Caring for the zero resistance filter

In order to be guaranteed to get an increase in power throughout the entire life of the “zero”, it is necessary to constantly monitor the condition of the filter. Namely, every five thousand kilometers, and if necessary, more often, the surface should be cleaned of dust and dirt using a special technology.

Maintenance of dry "nuleviks"

Such products must first be cleaned of adhering particles of dirt, dust, insect remains, using a brush with a soft bristle for this purpose. You need to act very carefully so as not to damage the delicate filter material. After mechanical cleaning, spray the working surfaces with a special detergent composition, wait 10-15 minutes, and then rinse the filter under a weak stream of clean water. Shake the filter gently to remove moisture. Drying with a hair dryer or household heaters is strongly not recommended. After the above manipulations, the air filter of zero resistance can be put in place and safely used.

Cleaning "wet" filters

The procedure for cleaning impregnated with a special compound "null" is almost the same as described above, with one exception - after all the manipulations, it is necessary to additionally treat the surface with an adhesive recommended by manufacturers.

Is a zero resistance filter necessary?

As a summary, we will answer the question that worries many motorists about whether it is worth installing a low-resistance air filter. Definitely worth it if the motor often runs on high revs And every horse counts. The benefits of such tuning are especially noticeable if the internal combustion engine was forced, the refinement of the intake and exhaust will allow you to purchase a ten percent increase in power. Installing a reduced filter is useful not only for a sports car, but also for a civilian car, since even if only slightly, it will still improve the engine. Moreover, you don’t have to sacrifice anything at the same time, and the procedure for replacing the filter core of a regular filter is quite simple.

However, once again we note that during installation it is very important to take into account the following nuances:

• firstly, you can only install a certified product that is not inferior in filtering quality to the factory "colleagues", otherwise the air flow sensors will fail very quickly, and the resource of the motor itself will significantly decrease;
• secondly, if the filter is not regularly maintained, then instead of a positive one, you can get the opposite effect.

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?

A task air filter installed in each car - to clear 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;
• is changing appearance space under the hood - it acquires greater sportiness.

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 install the "zero" because of which it is not able to perform its 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 zero filters, which are designed for mounting on various types of cars - with an injector or 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 null filter, you are taking a certain risk and you 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.

An ambiguous attitude towards tuning the air system is formed by motorists who want to get the most out of their car. This is due to the installation of such an element as an air filter of zero resistance (VFNS). Unlike professional athletes, who are unambiguous about such a detail, amateurs have not come to a consensus.

The name itself speaks about the functions of the product. In fact, according to manufacturers, it minimizes the resistance of air entering the engine to form an air-fuel mixture. Due to its design, the amount of air increases, and with it the mass of supplied oxygen increases. The purpose of installing this unit is to increase the power of the vehicle.

Installed filter

It is believed that nulevik gives an increase of about 5-7% of power. In terms of an average car, you get about 5 hp.

It is unlikely that such a parameter can be called significant. Not all experienced drivers will be able to feel such an increase. Therefore, the main buyers of new items are representatives of the younger generation of car owners. Most often, the device is equipped with cars of domestic manufacturers.

The installation of the VFNS is usually carried out during the tuning of the power plant. Because a filter without motor preparation will not bring the desired effect. It is recommended to put a straight-through exhaust, and only then mount the nulevik. Additionally changes throttle valve to a more powerful one. The “brains” are also being reflashed for an updated design.

As a result of the work done, it can be hoped that an additional five horses will be added to the power.

Variety of filter shapes

After performing such manipulations, the sound emitted by the engine will change slightly. A solid engine bass can amuse the vanity of young drivers, and will highlight the car's "voice" in the traffic stream.

Advantages and Disadvantages of Installing Zero Filters

In every case there are positive and Negative consequences. Let's try to evaluate the pros and cons of a zero-resistance filter installed in a car.

Pros:

• increasing the power of the car, when carrying out additional work with exhaust system;
• new, more "solid" sound from the engine compartment;
• an updated view of the engine compartment, stylized as a sports car.

Minuses:

• regular maintenance of the installed filter is necessary;
• cheap non-branded filters carry out poor-quality air purification, which negatively affects operation engine oil; it becomes dirty, and this leads to disastrous consequences for the engine as a whole.

Difference between regular and null filters

The performance of air purification by zero directly depends on its design features. Standard air filters are made from notoriously dense materials. Thanks to this, they qualitatively clean the air supplied to the system from various polluting particles of dust and debris. But at the same time, significant air resistance is obtained due to the high density of the filter layers.

The difference between filters

Zero filters are based on cotton fabric. An additional deterrent for debris is a special fabric impregnation. Thanks to this design, small particles of dust and dirt do not penetrate into the motor, but remain outside the filter.

In fact, cleaning occurs due to the adherence of debris, while nothing else interferes with the air.

This design does not create 100% cleaning. Also, if the filter is not cleaned in time, there will be more negative than positive from this installation.

Maintenance of Zero Resistance Filters

After installing the zero, you need to take care of it. It is required to wash and impregnate the filter with a certain fixed frequency of mileage. Used for impregnation special fluid which is purchased separately.

Nulevik flushing

You should not skip maintenance, otherwise the car will degrade its power characteristics, and fuel consumption will increase markedly.

The order of service is as follows:

• the filter must be removed from the car, then a brush with soft bristles or a brush with soft bristles is used to remove visible particles of dust and debris from the surface;
• a layer of impregnation from a branded bottle is applied to a dry, cleaned filter and left for 10-15 minutes to completely impregnate the fabric;
• now the nulevik is lowered into a container with water at room temperature and rinsed in it;
• removed from the container and placed under a weak flowing stream of water for rinsing;
• shake off excess water and put the device to dry for a short time;
• after that, the filter can be installed in place.

You need to know that drying with a hair dryer or similar intensive devices is not allowed.

Cleaning under running water

The average mileage between service is 8-10 thousand kilometers. If the operating conditions of the car involve traveling on dusty roads, then the mileage is reduced to 4-5 thousand kilometers.

For VFNS, about two dozen washing cycles are provided. Further, it is recommended to replace the zero resistance filter with a new one.

Self-made filter

The estimated price of the product in stores is from 500 to 3500 rubles, excluding the cost of impregnation. Not all car owners are willing to pay a rather big price for such an additional device. Therefore, craftsmen make a zero-resistance filter with their own hands in garage conditions. Most often, the VAZ classic or models of the old Muscovites act as an experimental car.

Step 1. Cut the filter cover to a diameter Step 2. Adjusting the filter cover to size Step 3. We clean the edges on the emery Step 3. We measure and fit sizes Step 4. Prepare the filter Step 5. Cut off the unnecessary intake pipe Step 5. Clean up the edges Step 6. Mount on the engine

Regular filters and body parts of car air systems are used as improvised materials. The alteration is carried out with the help of a grinder, emery, a file and diligence. The operating conditions apply approximately the same as for branded products. But installing such a part on a car is carried out at your own peril and risk. At the same time, no irreversible changes in the design are carried out, therefore, if desired, everything can be returned to its original position with “native” filters without damage.

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. The impregnation for the zero resistance filter causes the dust particles to settle successively 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 design of the element 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.

Figure 2. Air filter of zero resistance 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 mass air flow sensor. 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.

Hello! Next in line we have a rather relevant and interesting topic. After all, we will talk about the nulevik filter. Many have heard about such an air filter, but not everyone knows exactly what it is, what it is for, and what is the use of it.

Nulevik put instead of the air filter in a regular place. And here it is important to understand what such a device gives. Let me tell you right now, it has its pros and cons. But for objectivity, I will first try to tell you in detail about the device, and then summarize whether there is any benefit in this purchase, whether it is worth installing a nulevik on a car, on a moped, on some VAZ or on a carburetor, for example. After all, there are often craftsmen on the net who put the device for Pidburg and on Alpha, that is, on a scooter.

Don't forget to share your opinion. Especially if you have personal experience in the use of filters of zero resistance. That's the right way to call zeros.

Why is it needed

First, let's figure out what it is and what it is eaten with. A standard or conventional air filter is designed to clean the air entering the motor from all kinds of contaminants. It is due to air filtration that power is lost.

This is due to the fact that the cleaning elements in the filter design (usually a special paper) create resistance to air flow. This is not surprising since the filtration material is very dense. And the higher the resistance values, the more the final power is lost. As you know, an increase in power is achieved by increasing the amount of incoming air. This is where the zero-resistance filter comes into play.

Nulevik is an alternative to the standard cleaner. Its design is such that the device reduces intake resistance without sacrificing air purification itself. This results in an increase in power.

And then a logical question arises as to whether your Priora, VAZ 2112 or VAZ 2114 is worthy of a similar element? Is it worth buying a nulevik at all, wanting to slightly increase engine power?

Practice and research show that such a small tuning as setting zero allows you to get an increase of 3-5% power. If it's a low-power car, then you definitely won't experience a few horsepower gains. You won't see any difference in dynamics either. But the numbers will be higher than you can comfort yourself a little.

Key Benefits

Reading reviews about nuleviks, I met a lot of conflicting opinions. One put himself such a filter on the injector, and was very pleased. Another spent a lot of money on a K&N Zero and installed it, wanted a change, and ended up with wasted time. And there are many such examples.

I will say right away that ordering zero-resistance filters from auto shops is not a problem at all. The price of some models is quite adequate, therefore it is not difficult to buy and relatively inexpensive. But is it necessary to install such an element on a VAZ with your own hands, the question is extremely interesting.

Let's start with the good. Like any device, the nulevik has its pros and cons. The disadvantages include the cost compared to a conventional air filter and the need for constant cleaning.

As for the advantages, there are several.

• The power increases. Nulevik has a complex design that allows you to reduce resistance. This gives an increase in the amount of horsepower;
• Simultaneous cleaning efficiency. Although the resistance drops, this does not affect the quality of air purification;
• Replacement frequency. It is not necessary to change the nulevik as often as a regular filter. They are washable. This allows you to return performance characteristics fully;
• Increase in features. Let a little, but nulevik adds power and increases torque;
• Sound. For many, it is not power that is important, but the sound characteristic of powerful motors. Nulevik creates such an effect, and as a result, the car sounds very interesting.

To achieve what you want, you will have to remove the standard filter, and install a device of zero resistance in its place. What is better, buy and install with your own hands, or give the car to the masters, decide for yourself. In the second case, there will be a guarantee of quality and a well-chosen filter. The main thing is that the specialists themselves are qualified and reliable.

But there is a sense

There is a common misconception that after removing the filter and housing, it is possible to significantly increase engine power. This is completely untrue.

It is important to take into account here that when developing an engine, a fine calculation of the gas distribution phases is made, in which errors and filter losses are taken into account. And if dust starts to enter the engine, it will definitely not be able to work for a long time. It is imperative to have a fence that will prevent the penetration of contaminants. You can reduce the resistance by expanding the through holes. But then the quality of filtration will decrease.

Before looking for a product article and buying a nulevik for your motorcycle or car, remember one simple truth. For machines without power sports engine the cost of buying such a filter would be absolutely meaningless. You're just wasting a few thousand dollars. The only thing you get is a slightly modified motor sound.

Nuleviki are suitable only for sports cars and cars with powerful power plants. It is allowed to use such a filter on serial motors only in cases where a comprehensive revision is carried out. That is, a bore is made in the cylinders, an enlarged throttle valve is mounted, sports camshafts are installed, etc. With them, you can also put a nulevik in the kit.

Maintenance question

If you still decide to install a nulevik instead of a standard type air filter, then you will have to take extra care of it. The essence of care is cleaning and periodic impregnation with solutions. Moreover, when leaving, a certain technology is strictly observed.

If this is not done, the car will significantly increase fuel consumption, power will drop and the car will begin to react poorly to increasing speed when the gas pedal is pressed.

You need:

• remove the filter;
• clean dirt with a soft brush;
• remove dirt from the landing nest;
• rinse the filter with water;
• shake a few times, do not dry;
• apply cleaning agent on both sides;
