The manufacturer recommends changing iridium spark plugs every 90,000 kilometers, at least as it is written in Mitsubishi service manuals. In fact, the Rolf service center recommends changing them every 60,000 kilometers, most likely this is due to the poor quality of gasoline in Russia.

To replace spark plugs:

1. Long socket 16 or candle key 16 with a latch, it is desirable that the outer diameter of the key be as small as possible, otherwise it will not fit into the candle wells.
2. Torx E10 socket for 1.5 liter engine. For engines with a volume of 1.8 and 2.0, a conventional 10 hex socket is used.

Please note that when buying original Mitsubishi spark plugs, the box will contain Bosch spark plugs (for a 1.5 liter engine), and NGK or Denso (for a 1.8 and 2.0 liter engine). The fact is that Mitsubishi in this case is only a packer, and the above companies are engaged in the production of candles. Knowing this, for the same amount you can buy two sets of candles instead of one.

Let's start replacing spark plugs on Mitsubishi Lancer X

1. The first step is to open the hood and remove the top plastic engine cover by pulling it up.

2. If there is a large amount of dust and debris on the engine, it is advisable to blow everything thoroughly. After that, it is already possible to start unscrewing the ignition coil mounting bolts using a 10 or Torx E10 socket, depending on the type of bolts.

3. Now it is necessary to disconnect the plug of the low-voltage input of the ignition coil, after that we pull the coil up and set it aside.

4. Immediately below the coil will be a spark plug, which must be unscrewed using a spark plug wrench with a magnetic or plastic retainer. If you are using a conventional extended socket, the spark plug can be pulled out using the fuel hose:

5. We twist the new spark plug into place. If a torque wrench is available, it is advisable to tighten the candle with a torque of 25-30 N m

6. Reinstall the parts in the reverse order of removal.

Replacing candles on a Mitsubishi Lancer X is a very simple matter, you can do it in a few minutes. The main thing is to strictly follow the instructions and not deviate from it. If you have never done this before, it is better to ask someone to help the first time.
Service books from official manufacturer they say that the replacement of candles is best done every 90,000 kilometers with iride candles. In our country, this figure is less - 60,000 km, because the quality of gasoline in most of the region leaves much to be desired. If the candles are ordinary, then it is better every 30,000 kilometers.

What do you need to replace?

A key for 16 or a special candle key. It will be good if the outer diameter of the hook is not large - then the tool will easily crawl into the candle wells.
If you have a 1.5 liter engine, then you will also need a TORX E10 socket head, if 1.8 or 2, then just a 10 hexagon.
A set of new candles - 4 pieces.

Procedure:

1. Open the hood and remove the plastic engine cover. You do not need to unscrew anything - just pull the cover up.

2. If the engine is dirty, in dust or debris, then it is better to rinse and wipe everything properly. Now you can safely unscrew the bolts that secure the ignition coils. To do this, you just need an E10 socket wrench or a simple 10 head.

3. Now it will be necessary to disconnect the wire plug from the ignition coil. Removing the coil is simple - pull its top and set it aside so as not to lose or step on it.

4. Immediately below the coil we see what we are looking for. It is unscrewed with a special candle key or latch. When using a simple socket, the spark plug can be removed with a fuel hose (as pictured)

5. We put new candles. It is better to first twist it with your hand in order to feel whether the candle has got into the thread or not. If you feel that it is “tight”, then it is better not to make an effort, but to unscrew it and try again. Well, if you have a special torque wrench: you will need to tighten with a torque of 25 Nm

6. Install everything back in reverse order.

Now, which candles to choose? For different power units suitable for different candles.
For a 1.5 liter engine, this is Mitsubishi MN176628 (original) or Bosch 0 242 235 769.
For engines of 1.8 or 2.0 liters - original Mitsubishi MN163236, Mitsubishi MN163807 or NGK FR6EI,
Denso K20PSR-B8.

Remember that even if you buy an original product from Mitsubishi, the box still contains spark plugs from Bosch or NGK, Denso. There are no problems: Mitsubishi just packs candles, and partner companies are engaged in production.

Replacing spark plugs on a Mitsubishi Lancer 10 is a standard procedure that is carried out every two years or when a mileage of 60 thousand km is accumulated. (iridium candles - 90 thousand km).

But due to the fact that in most cases the quality of gasoline leaves much to be desired, it is recommended to change them more often - after accumulating a run of 30 thousand km. Spark plugs can be replaced service center or on your own. This is not a complicated procedure that takes a few minutes.

But if you are not an expert or you do not have necessary tools it's easier to turn to professionals.

What parts to choose - original or non-original

Many owners of Lancer 10 are wondering which candles to put on their car - more expensive original ones or cheap non-original ones. It may seem that native parts must be better, but this is not entirely true. In fact, in most cases original candles ignitions are made by the same companies as non-original ones.

The well-known Japanese manufacturer NGK supplies spark plugs to many brands, including Mitsubishi. That is, there is no difference between a spare part offered by this company and any other with the same marking. The overpricing is associated with pricing policy group and warranty costs. In fact, non-original candles are the same original ones only without the logo on the package.

On the other hand, there are very cheap candles. Chinese made. It is better not to use such spare parts at all, as their quality is lame. The best option- these are candles made by serious companies such as NGK, BOSCH.

Where can I find spare parts

You can find spark plugs for Lancer X at a warranty service center or at a service station. Experts will quickly tell you exactly what kind of candles you need and help with the installation. But if you decide to choose your own parts for the car, you can search on the Internet.

In order to quickly find the required spare part, you will need to know its OEM number. The original market number of the product is a code that identifies each specific part. The OEM number consists of a combination of letters and numbers. Each manufacturer has its own product numbering system.

There are many spare parts catalogs on the Internet. Having entered one of them, you need to enter the OEM number in the search field and a list of all options will immediately become available to you.

Thus, you can compare candles by cost and choose from the proposed manufacturers. Approximately also, you can find the necessary parts using the VIN code (body number) of the car. To do this, in the catalog you need to search for this code. All parts from this car model will be knocked out.

If you do not know either the OEM number of the spark plugs or the body number, then you can search by the year of manufacture and modification of your car.

How to make a replacement

In order to replace old candles with new ones, you will need the following tools:

• candle wrench for 14 with an elastic band inside;
• ratchet wrench with 10 head;
• screwdriver with a flat tip.

All candles must be placed in order - one after the other. That is, we first twist the first completely and only then proceed to the second.

The first step is to remove the protective cover. To do this, unscrew the three mounting bolts. After, using a screwdriver, the connector is removed and the bolt holding the ignition coil is unscrewed. Next, you need to pull out the ignition coil and insert the spark plug key until it clicks.

After that, you can start twisting the candle. After releasing the connector, you need to screw in a new candle and put the ignition coil in place, as well as tighten the mounting bolt and connect the connector. Thus, all candles are replaced. Tighten the candle carefully so as not to strip the threads, but at the same time firmly so that there is no poor heat transfer.
