Replacing spark plugs for Lada Largus 16 and 8 valves. Articles, photos, videos

LADA Largus has been produced since 2012. The car was equipped only with gasoline engines. Their line is not very wide, represented only by a volume of 1.6 liters, and these are mainly French engines from Renault - K4M (16-valve) and K7M (8 valves). Until 2015, the Lada Largus was also equipped with the Russian 8-valve power unit VAZ-11189.

Spark plugs for Largus do not have a wide variety, and differ depending on the engine modification. There are also differences in article numbers depending on the manufacturer. All original spark plugs are supplied in branded boxes from Renault. The main manufacturers are EYQUEM (France) and Engels Plant (Russia).

Spark plugs Lada Largus for 8- and 16-valve engines

Spark plugs for Largus 1.6 differ from each other only depending on how many valves the engine has. On cars with 8-valve engines (K7M, VAZ-11189), the manufacturer installs 7700500168 - where they are used, what sizes”>spark plugs 7700500168. They have a regular nickel central electrode, and two side electrodes. The same candles can be found directly from the manufacturer EYQUEM under the article number RFC58LZ2E. An analogue from a Russian manufacturer has article number 224013682R. These models are no different from each other and are interchangeable.

On Largus with a 16-valve K4M engine, spark plugs are installed under article number 7700500155. Unlike the previous spare part, these spark plugs have one side electrode, but they are nickel. The French manufacturer EYQUEM has the article number RFN58LZ. The Russian analogue has article number 224018651R.

On a Largus with a 16-valve engine, you can also install spark plugs with 2 side electrodes from an 8-valve engine, but not vice versa. On 8-valve valves, only 2-pin ones are installed. As drivers note, spark plugs with 2 side electrodes slightly improve engine performance by reducing vibration.

The most commonly used substitutes are presented below.

Since the manufacturer installs conventional nickel spark plugs on their cars, which have a short service life, Largus owners often resort to installing more expensive iridium spark plugs. Their service life is often 3-4 times longer than nickel ones, and in addition they also slightly improve the dynamic performance of the engine. For 8 valve Lada Largus, the most popular model is Denso IW20 at a price of 670 rubles/piece. And for 16-valve cars it will be Denso IK20 RUB 520/piece.

When to change spark plugs on Lada Largus?

According to the LADA Largus maintenance regulations, spark plugs are changed every 30 thousand km. But, as most drivers note, the actual service life of original spark plugs often approaches the 50 thousand km mark. If iridium spark plugs are installed, they usually last up to 100 - 120 thousand km.

Lada Largus spark plugs are a very important element of the ignition system of a domestic station wagon. Not only reliable engine starting in the cold season, but also stable engine operation, fuel consumption, dynamics and many other factors depend on timely replacement and correct selection of spark plugs.

As you know, over the years Largus has been equipped with K7M, K4M, 11189 and 21129 engines. Let's figure out what spark plugs are installed on these engines and how to change them. Let's start with the most modern, in my opinion, engine 21129 1.6 liter 16-valve.

Purpose and location of candles in Largus

Applying high voltage to the electrodes causes a spark and ignition of the fuel. The design is quite simple, but the materials from which it is made have special requirements. The electrodes must be made of a heat-resistant alloy that conducts current well. It is important that the insulator has high dielectric characteristics along with increased heat resistance. The housing must have a minimum coefficient of thermal expansion, otherwise the spark plug cannot be removed.

Devices for igniting the air-fuel mixture on all car models are located on the cylinder head. An important feature: when installing them, the central and side electrodes must be located directly in the combustion chamber. The formation of a spark occurs as a result of the supply of high voltage by a pulse transformer.

On K4M engines with a 16-valve gas distribution mechanism, this device is installed on each spark plug. This is in contrast to the 8-valve K7M engines, where there is only one ignition coil.

Instructions for repairing and replacing the ignition coil

Removing and replacing short circuits is carried out according to the following algorithm:

1. First you need to de-energize the car by disconnecting the negative terminal of the battery.
2. Having released the latch, you need to disconnect the block with the wires coming from the controller.
3. Then the high-voltage wires should be disconnected from the short circuit.
4. Next, unscrew the screws securing the ignition module to the bracket and remove it from the bracket.
5. The new module is installed in place of the old one. Next, perform the reverse steps of removal.

Spark plug replacement interval for Lada Largus

Regardless of the engine and configuration, Lada Largus spark plugs are changed after 30 thousand kilometers or after 24 months. Depending on what comes first.

However, it is better to change simple nickel spark plugs a little earlier, especially when it comes to 16-valve engines. I would recommend replacing it after 15-20 thousand kilometers.

If it is difficult to start the engine, when the engine stalls or stalls, it is worth checking the spark plugs. Most likely, they have exhausted their resource and need to be replaced. Many owners of the Lada Largus car install analogues after the original spark plugs coming from the factory. More affordable, reliable or durable.

We have selected, in our opinion, the best options for replacing spark plugs on Lada Largus. Let’s immediately make a reservation that if the engine is 8-valve, you can choose any budget model. There is little point in buying expensive iridium models. Their effectiveness becomes noticeable on more complex engines with 16 valves. And in terms of overall dimensions, everything should be clear: the wrench head is 16 mm, the thread length is 19, and its size is M-14. Properly selected spark plugs are the key to stable operation of the exhaust system, catalyst and engine as a whole.

Replacing Renault Logan spark plugs: frequency and choice of spark plugs

The Renault Logan car first rolled off the factory assembly line in 2004. This model is presented on the market in several generations, equipped with diesel and gasoline power units. You can buy a car at Russian dealership showrooms with a gasoline-powered engine with a volume of 1.4 and 1.6 liters (equipped with first-generation models), 1.6 and 1.2 (equipped with second-generation models). The designated power units are widely used in Russia, so we will talk about spark plugs for these engines.

Let us immediately note that the spark plugs for both generations of the model differ in how many valves the engine has. In other parameters there is no clear division, even taking into account the year of manufacture of the car. Drivers who own this model should remember that the original spark plugs are marked by Renault on the box. The package may contain a part manufactured by Eyquem or Champion.

Spark plugs Renault Logan

The first generation Renault Logan cars on the Russian car market received a 1.4 engine (K7J) and a 1.6 power unit (K7M, K4M) under the hood.
The first operates on eight valves. The second one is at sixteen. The updated generation of the model received the already popular 1.6 engine (K4M) and a new unit (much less common) 1.2-liter D4F engine. The spark plugs for engines of the first generation model are the same. The manufacturer equips a car with an eight-valve engine with spark plugs having article number 7700500168. Sixteen-valve engines are equipped with spark plugs 7700500155. The main difference is in the number of electrodes. If the first spark plugs received two side electrodes, then the second ones only had one. All other characteristics of spark plugs for Renault Logan, including size, gap, heat rating and thread, are identical.

To the side stands the 1.2-liter D4F engine, mounted in the engine compartment in second-generation cars. Here you can only install Renault Logan spark plugs marked 224018760R, which have one side electrode. The differences lie in all parameters, including size.

Analogs

As analogues of the original spark plug for Logan 1.6 marked 7700500168, you can use:

• Bosch products with index 0241235751;
• Denso spark plugs and marked K20TXR.

For those drivers who drive cars with a sixteen-valve engine, if there is no opportunity or desire to find original spark plugs for Logan 1.6, you can consider the following analogues:

• Bosch spark plugs with index 0242235666;
• BERU Z 193 spark plugs. An excellent option for those Renault Logan owners who are not used to frequently taking their car for service or looking under the hood on their own to replace spark plugs would be to use iridium spare parts instead of standard nickel ones. The main difference is the service life, which increases four times. Many motorists note an increase in the dynamic characteristics of the car after replacing nickel spark plugs with iridium spark plugs.

The most popular among Logan owners equipped with a 1.6 and 1.4 liter engine are spark plugs from the Japanese manufacturer Denso IK20TT. Owners of cars with a 1.2-liter D4F installed under the hood of the second generation model use parts of the same brand, but with the index IXEH20TT. There is another option when Renault Logan owners use NGK P spark plugs marked 6418.

When to change spark plugs

The frequency of replacing spark plugs on Renault Logan should be observed at the mileage mark of every 15 thousand. However, car owners note that the part has twice the service life. Therefore, all situations are individual and spark plugs should be changed if necessary.

The process of replacing spark plugs

Since the most popular engine installed on Logan in Russia is the K4M, it is worth paying attention to the process of replacing spark plugs.

Replacing spark plugs on Renault Logan begins with removing the coils. Naturally, each cylinder has its own coil.

The coils must be cleaned of dirt and dust with strong air pressure.

Now you can remove the connectors. This is done by simply pressing the flag and pulling the connector itself down.

The wires should be put aside so that they do not interfere with the process of replacing spark plugs.

The connectors have been removed, the wires have been removed, and the coils can be unscrewed. To do this, it is best to arm yourself with a wrench and a 8-mm head. Often, coils are secured with bolts of this diameter.

When the coils are unscrewed, all that remains is to pull them up. Sometimes this is easy to do, and sometimes it is very difficult, because in the factory the part is fixed with mastic. If the coil does not work, you can use a screwdriver and carefully pry off the protrusion at the corner.

The main thing is to be careful, as the part can be damaged.

When the coils are removed, it is worth checking them for traces of oil and water (there should not be any).

Next, the wells are purged, and the process of unscrewing the old spark plugs begins. To remove spark plugs on a Renault Logan, use a 16mm tubular spark plug wrench or a 16mm socket. You may need to apply a little force until the spark plug comes off. Then the process becomes easier.

Unscrewed candles can be removed from the well in any available way. The ideal tool for this purpose is tweezers.

Remember that before installing new spark plugs, you must check the electrode for external damage. Spark plugs come in a box without special protective covers, so very often the contacts are bent.

It is advisable to lower new candles into the well using a special tool so as not to throw them.

All that remains is to tighten the parts with a wrench until they stop, and then tighten them with a wrench. One of the elements is an o-ring. It needs to be compressed. If you don’t have a torque wrench at hand, then turn the spark plug to an angle of 90 degrees.

The candles are in place. We need to install the coils. First we install the bolt, and then the coil.

Assembly is carried out in the reverse order of disassembly.

  On a Lada Largus with a 16-valve engine, it is possible to install spark plugs with two side electrodes from an eight-valve power unit. However, there is no interchangeability in the opposite direction.

  Lada Largus is equipped with relatively cheap nickel spark plugs from the factory. At the same time, the manufacturer allows the use of iridium consumables on the machine. Such spark plugs have a longer service life and ignite the fuel-air mixture better. One good option for an eight-valve engine is the Denso IW20, and for a 16-valve engine the Denso IK20.

Which spark plugs are suitable for a 16 cl K4M engine?

If you have a Lada Largus with a 16 valve engine, the original Renault spark plugs 7700500155 will suit you. The official analogues of these spark plugs are Motrio 224018651R. If you can’t buy such candles from us, you can get by with analogues from other manufacturers:

• BOSCH FR 7 LDC+ 0242235668 price from 600 rubles per set
• DENSO K20TT K20TT#4 price per set from 550 rub.
• CHAMPION RC87YCL
• SAGEM RFN58LZ

The above spark plugs are suitable for a 1.6 16 cl engine. K4M 102 (105) hp To replace the spark plugs, we need a spark plug wrench with a size of 16 and a socket with a size of 8 in order to unscrew the ignition coils.

The difference between replacing spark plugs on 16-cl and 8-cl engines is that on 16-valve engines each spark plug has a separate ignition coil, and on 8-valve engines there is only one coil. Also, spark plugs have different potassium numbers, plug types, diameters and gaps.

Recommendations for replacement intervals

Officially, replacement of original spark plugs on Lada Largus is required every 30 thousand km. When used in domestic conditions, the service life of consumables barely exceeds 15 thousand km. The reason for this is the low quality of the fuel sold.

During operation, unscheduled replacement of spark plugs may be required. The main reasons for carrying it out are:

it is impossible to adjust the gap; the spark plug has one of the damages shown in the image below.

When replacement is required

The spark plugs should be replaced in accordance with the vehicle maintenance regulations, that is, every 15 thousand km. These are the requirements when it comes to standard spare parts supplied by the manufacturer. There are many innovative types of these platinum plated or iridium plated parts available in the aftermarket today. In such cases, their service life is much longer.

Spark plugs must be replaced not only as planned or for preventive purposes, but also due to malfunctions. This could be contamination of the skirt with carbon deposits or oil when driving on a cold engine, or coking of the thermal cone caused by increased oil consumption. If replacement is not done in a timely manner, the electrodes may burn out, resulting in an increase in the gap and an insulation breakdown. One of the causes of problems may be a manufacturing defect, leading to the passage of gases through the insulator and housing. If these faults are present, the car does not start well or the engine begins to stall. This is unacceptable for further operation of the car - you need to find the damaged spark plug and replace it.

Spark plugs for Lada Largus

When buying candles on Lada Largus, you do not just purchase the necessary consumables. The correct selection of an element, insignificant in size and cost, determines the behavior of the car on the road, the cost of its maintenance, and your mood.

Correctly selected spark plugs directly affect the speed, dynamic, and performance characteristics of the car.

The spark plugs included in the ignition system of a gasoline internal combustion engine serve to generate an electrical discharge. Under the influence of incoming voltage, a spark is formed between their electrodes. The subsequent ignition of the fuel mixture provides the energy necessary for the vehicle to move.

Selection of candles for Largus

Faulty spark plugs can cause a lot of problems and hassle. The most serious ones include the following:. All this makes the choice of spark plugs for Lada Largus not just part of the next technical or seasonal maintenance. Lada Largus engines allow the use of spark plugs from different manufacturers, models, and operating data.

What spark plugs are installed on Largus

A note about what spark plugs are installed on the 8-valve Largus from the factory;
what spark plugs the manufacturer recommends; where you can buy original spark plugs at an affordable price. The first 15 thousand on my Gus are long gone. And this is the mileage at which the car undergoes its first maintenance. At the same time, one of the mandatory service work was the replacement of spark plugs. The procedure is not complicated and took me no more than 20 minutes.

But before that the question arose: “What replacement candles should I buy?” Having opened the hood and unscrewing one of the spark plugs, I found out that my 8 valve valve has two-pin spark plugs Eyquem (RFC58LZ2E), made in France. The gap between the electrodes is 0.95 mm (± 0.05 mm). The country of manufacture “Made in France” is indicated on the case.

Here is a photo of one of them:

Where can I buy?

One of the large Moscow online stores, from whose catalog I select spare parts for Largus, gave me the following information on candles:

• Article 224013682R — spark plug for 8 cells Lada Largus (7700500168), 2 electrodes, Romania, original
• Article 224018651R — spark plug for 16 cl Lada Largus (replacement 7700500155), 1 electrode, France, original

I ordered according to the first article, i.e. 224013682R. The purchased candles corresponded to the original ones, with the only difference being that the country of their manufacture was Russia. Information about this is indicated on the packaging. On the body of the spark plug itself are indicated: letter markings of the Renault company, alphanumeric code. Country not specified.

This is what the packaging of candles 224013682R looks like:

And here's the candle itself:

I installed these spark plugs after the first maintenance. I also continue to use them at every scheduled replacement. There are already four technical inspections under my belt. The mileage has exceeded 60 thousand. The flight is normal.

The only question I have left is, what kind of spark plugs come under article number 7700500168 (7700500155)? Maybe just the original French ones? I'll try to buy one of these someday and find out what kind of animal it is.

Factory recommendations

If we contact the manufacturer directly, he redirects us to the operating manual and service book of the car, where not a word is said about spark plugs. To top it off, he sends it to the dealer.

If you look at the Largus manual, then for the K7J and K7M engines Champion RYCLC87 and SAGEM RFN58LZ spark plugs are recommended, and without division into 8-cl and 16-cl.
