Which spark plugs are best for a VAZ 2114 injector with 8 valves?

One of the most popular domestic cars. Built on the VAZ 2109 platform. Sporty appearance, good technical performance, excellent cornering, excellent weight control - these are its main characteristics.

Initially, the model was presented with a 1.5 liter 8 valve engine. Ten years ago, a car appeared with a 16-valve 1.6-liter engine and 77 horsepower. Two years later, the manufacturer increased the power to 89, in 2010 to 98. The transmission is 5-speed, fuel consumption in the city is 7 liters, on the highway - about 9 liters per 100 km.

The operation of an internal combustion engine depends on the air-fuel mixture and its ignition. The throttle, air filter and spark plugs are responsible for this. The latter lose their useful properties during operation and require replacement with new ones.

Signs of faulty spark plugs

Signs of faulty spark plugs can include many different factors, which will be similar to problems in the fuel supply, problems with the ignition module and high-voltage wires.

It is necessary to check the spark plugs if the following signs of malfunction appear on your car:

• The engine is running rough (one of the cylinders is not working);
• The car's dynamics disappeared;
• Difficulty starting the engine;
• Fuel consumption has increased;

When to change spark plugs in Lada (VAZ) 2114

Spark plugs are not replaced often. If the car works without interruptions, then the procedure is carried out as planned. The manufacturer recommends installing new spare parts every 30 thousand km. This is stated in the VAZ 2114 operating manual.

Good factory spark plugs can last longer, up to 60 thousand km. But experts do not recommend using them for so long. As practice shows, it is advisable to change spark plugs every 20 thousand kilometers, and 10 in winter.

VAZ 2113, 2114 and 2115 (Samara-2 series) are very similar in design, have a common platform and are equipped with the same engines - 1.5 (VAZ-2111, 77 hp) and 1.6 (VAZ-21114, 82 hp . or VAZ-11183, 81 hp).

Spark plugs for VAZ 2113/2114/2115 do not differ in any way depending on the configuration, year of manufacture of the car, or the installed engine. The same spark plugs are installed on all 3 cars. The original manufacturer is the Russian company “E3”, Engels. What is noteworthy is that the production facilities of this company belong to Bosch. Spark plugs for VAZ 2113, 2114, 2115 – which ones to install?

On VAZ 2113/2114/2115 with 1.5 and 1.6 liter engines, spark plugs should always be placed under article number 21110-3707010-86. It is also found under other numbers - 21110-3707010-00 or 2111-3707010. In fact, these are all the same spark plug. In the manufacturer's catalogs it has the article number A17DVRM. This spark plug has a central nickel electrode, single-contact, short thread, tightening torque - 22 Nm.

The dimensions of the original spark plug are shown below.

* according to Champion nomenclature (Russian standard)

Original candles, as a rule, are usually sold in branded packaging from LADA. Less often you can find them directly from the manufacturer - the Engels plant. They come from the manufacturer a little cheaper. The reviews from most drivers about this spare part are positive, and there are not too many fakes on the market, due to the fact that they do not have a very high price.

What analogues are there?

The most famous substitutes for the originals from other manufacturers are presented below.

In addition to conventional (nickel) analogues, more modern platinum or iridium spark plugs are also somewhat popular. They are installed to achieve a slight improvement in the dynamic characteristics of the engine. This is achieved thanks to a thinner electrode than nickel models. In addition, they last several times longer. For VAZ 2113, 2114 and 2115, the most popular are platinum Bosch 0242235540 at 200 rubles/piece, or iridium DENSO IW20TT, 610 rubles/piece.

When to change spark plugs on a VAZ 2113/2114/2115?

According to the maintenance regulations for VAZ 2115, 2114 and 2113, spark plugs must be changed every 30 thousand km. But, as the experience of drivers shows, this period needs to be reduced by half on average, and in fact, replacement needs to be done every 15 thousand km. This is influenced by many factors, the main ones being fuel quality and operating conditions.

DIY replacement instructions

Replacing spark plugs on VAZ 2114 and 2115 is not a complicated process. This work can be performed by any motorist, following the step-by-step instructions given below.

Tools and materials

To carry out the procedure you need to prepare:

• key for removing protection;
• a set of round probes;
• spark plug key;
• new set of SZ.

To avoid counterfeiting, you should purchase original products.

The process of dismantling and replacing SZ

The procedure for removing and replacing spark plugs should be carried out on a cool engine to avoid burns.

The process itself consists of the following steps:

1. First you need to open the hood. Then you need to remove the protection from the engine, if present.
2. After removing the decorative trim, you need to remove the protective caps with high-voltage wires that are placed on the contacts. The caps should be removed carefully so as not to damage the wiring.
3. The areas near the NW should be cleared of dirt so that they do not get into the engine cylinders.
4. Now, using a spark plug wrench, you need to unscrew the S3 from the cylinder head. You can start twisting from any side. First you need to move it from the dead center, and then you can carefully unscrew the SZ from the socket.
5. Having turned out the old SZ, you need to wipe the thread with a rag.
6. Before screwing in new products, it is advisable to check the gap on each of them. For cars with an injector, it should be from 1 to 1.13 mm.
7. Installing the SZ is the same simple procedure as unscrewing; it is carried out in the reverse order. New products are placed in the seats of old candles. You need to screw it in carefully so as not to damage the threads in the cylinder head or on the product.
8. Next you need to put on the ends of the high-voltage wires. In this case, you need to make sure that the numbers of the wires that are printed on them match.
9. At the final stage, the decorative overlay is returned to its place.

After replacing the SZ, it is necessary to observe how the engine operates. If it works intermittently, it is possible that one of the SZ has defects. To detect it, you need to sequentially disconnect each high-voltage wire. A faulty spark plug should be replaced.

Price issue

High-quality products always cost more. Domestic products are several times cheaper, but the quality leaves much to be desired. Therefore, it is worth buying imported candles that will last much longer than domestic ones. At the same time, the service life of the engine will be extended, and fuel will be consumed more economically.

We choose which spark plugs are best for the 8-valve VAZ-2114: injector and spark plugs for it

In the ignition system of the VAZ-2114, spark plugs are in the leading place, because it depends on them how the engine starts after turning the ignition key. Therefore, it is to this detail, like no other, that much more attention should be paid during selection. And in this article we will tell you in detail about the design of the spark plug for the VAZ-2114, as well as how to choose the right one.

Measuring the gap and correcting it

Before you start adjusting the clearance value, you should first measure it accurately. To do this you will need a tool such as a probe. They are sold in the form of a set of thin steel plates with a precisely known size, mounted on one axis (like a folding knife).

The gap of the spark plugs of a VAZ 2114 injector 8 valves is measured according to the following scheme:

1. Disconnect high-voltage wires.
2. Select a feeler gauge with a thickness of exactly 1 mm and insert it into the gap.
3. If it enters with little force, but is slightly pinched between the output electrodes, then the gap is correct.
4. If the probe passes easily and does not encounter resistance, then the gap is large and you should take a larger probe.
5. If the measured clearance is more than 1.15 mm, then it will have to be adjusted.
6. The same applies to the situation when a 1 mm feeler gauge does not fit into the gap at all.

If after measurements it is discovered that the electrodes are too far apart, it will be necessary to bring them closer together. To do this, you will have to slightly bend the upper electrode and repeat the measurements again (and so on, until the required gap is achieved). If the gap turns out to be small, then the upper electrode, on the contrary, will need to be slightly bent upward.

It is important to remember that you cannot apply too much force to the spark plug electrode. It can break off very easily, and then there will be no choice but to completely replace the spark plug with a new one.

It should also be noted that the gaps on the VAZ 2114 injector spark plugs should be checked even after purchasing them in a store. After all, sometimes even spark plugs that have just arrived from the factory already have the wrong clearance value.

Features and design of the VAZ-2114 spark plug

Bosch spark plugs with white carbon removed from a VAZ-2114

Spark plugs for VAZ cars, and VAZ-2114 in particular, are no different from each other; in the same way, when they receive a 24 kV they generate a spark, thereby igniting the fuel in the combustion chamber. However, the main and most important structural element in each spark plug will be the central electrode, because it will ensure ignition of the fuel at a certain stage of startup.

The electrode must be made of heat-resistant, plastic and corrosion-resistant material.

It is usually made from all kinds of nickel alloys, but models with a more expensive price tag, in order to increase efficiency, can contain palladium, copper, iridium, platinum, silver and even gold. All this, according to manufacturers, was created for easier starting and the acquisition of individual properties of the candle.

When to change spark plugs?

If you want to change the spark plugs, then this issue should be approached extremely carefully and thoroughly, because the efficiency of their operation, overall fuel consumption and the transmitted power from the engine to the wheels depend on this choice.

• Numerous tests show that correctly selected spark plugs for a certain type of engine not only extend its overall service life, but also improve its performance.

Breakdown on the spark plug insulator

The manual from the VAZ-2114 states that the spark plugs must be changed every 30,000 kilometers , because after this the wear of the electrodes of the factory spark plugs changes and the car behaves completely differently on the road, due to an increase in fuel consumption and a decrease in power.

The condition of the spark plug and the ignition system can be determined with confidence by its appearance, depending on the condition of the electrode (presence of soot, soot, color - approx.).

This table will help you roughly find out what kind of soot it is:

Candles with different types of soot

Checking the spark plugs

Checking spark plugs is quite simple; their condition can even be assessed visually. To do this, just unscrew the spark plugs and check their condition and compare them with the picture below.

Even if the spark plug is externally in excellent condition, this does not mean that it is working properly. To definitely ensure that the spark plug is working properly, you need to replace it with a new one or swap it with a spark plug from another cylinder. If this spark plug does not work on another cylinder, then there is a breakdown in it, and if the spark plug starts working, then most likely the problem is not in the spark plug.

Which spark plugs are best for the VAZ-2114 (survey)?

Today, the choice of spark plugs is very large, and choosing the ones that need to be installed is not so easy. On most forums, owners of VAZ-2114 cars are most often advised, “Finwhale” “Champion” “Brisk Premium” “Bosch Platinum”, “DENSO”.

Remember that the best spark and the greatest amount of heat will be given by the spark plug that has the thinnest electrode, 0.4-0.8 mm in size, and they are usually made from alloys of iridium, platinum, palladium and gold.

Also, the situation with a spark that has a coating of platinum, silver or gold on its body has the best effect. For comparison, the “stock” spark plug from DVRM has a thickness of 2.5 mm, while on imported analogues it barely exceeds 0.6-0.8 mm, so there is no point in talking about any competition here.

Video about how to avoid falling into fake candles

Pay special attention to the integrity of the packaging, as well as the cost of the goods, because counterfeits, which are quite common today, can be sold at a discount from the average market price. Therefore, always remove each candle from its individual box and inspect it more carefully.

Other problems with spark plugs and their diagnosis

A very common problem that occurs even with new spark plugs is their “flooding”. It can be either oil or fuel. There can be a variety of reasons for this phenomenon - from the cold season and incorrect clearance in the spark plugs themselves to engine wear. That is why you should pay special attention to filling spark plugs and conduct timely troubleshooting.

But what to do with the most damaged candle? Of course - cleanse. But not the way most motorists do it. The first thing you should never do is clean it with sandpaper (especially with a coarse abrasive). Although the spark plug will start working, it will wear out faster than expected.

The second, also popular, and also not very suitable method is calcination with gas (on a stove burner or using a burner). Despite the fact that the candle will quickly return to working condition, its wear will be even greater than when using sandpaper.

A flooded candle should be cleaned only in the following ways that are safe for it:

• strong solvents (kerosene or acetone);
• a steel or (better) brass brush with soft bristles;
• a weak solution of vinegar or electrolyte (place the candle in it for an hour, then rinse with a solution of soda or plenty of water, then dry);
• rust converter (soak the candle for a short time, then remove the carbon deposits with a wooden stick. At the end of the procedure, rinse with water and dry);
• a device for ultrasonic cleaning (although the latter is found mainly in car repair shops and is not readily available to ordinary car enthusiasts).

Using the above methods, you will not only quickly clean a flooded candle, but also maintain its functionality for a long time.

TOP 10 best spark plugs for VAZ (Lada)

The most common type is gasoline cars, which require full maintenance. Usually a simple part like spark plugs doesn't raise many questions. However, the unit requires more attention than most motorists think. The stability of the engine and the service life of the ignition system depend on the correct choice.

In 2022, there are a large number of models and companies on the market that, in their opinion, produce the best spark plugs for VAZ and other car models. But it is not always the case.

Rating of the best manufacturers of spark plugs for carburetor cars VAZ-2112, 2115 and Niva

Since the Niva and some VAZ models (2101-2107, 2112 and 2115) have a fairly large number of similar parts in their design (this means only cars with a carburetor), the same spark plugs are quite suitable for them. Let's look at the best manufacturers of spark plugs for carburetor VAZ 2112, 2115 and Niva:

1. Bosch W7DTC. When using them, very stable engine operation and a slight increase in its power are observed. Quite a lot of fuel is consumed.
2. Brisk LR15TC. The most budget option of all those presented on the list. Candles show good results during operation. Fuel consumption is slightly higher when using them compared to other options, however, for its price category this is a quite good product.
3. NGK BUR6E. When using them, the engine runs quite steadily. The candles are practically non-toxic, made of very high quality, making them resistant to wear. At maximum open throttle, engine power is increased.
4. Champion N9BYC4. The spark plugs in their design contain three side electrodes. They perfectly reduce fuel consumption, are resistant to wear, and slightly increase engine power.

Which spark plugs for VAZ are better to choose?

There are a large number of different modifications of the part, which complicates life for motorists. The problem is that each motor is designed for a specific type of spark plug. If you supply the wrong part, a number of negative consequences can arise.

1. Misfire of the mixture due to the gap between the electrodes of the element being too wide.
2. Interruptions in the operation of the internal combustion engine caused by too low spark power.
3. Instant failure of the device due to too much electrode protrusion.

Also, depending on the inconsistencies present, other malfunctions may “pop up” that reduce the comfort of using the car.

What to look for when choosing.

Specialists from the AvtoVAZ plant recommend selecting spark plugs according to a number of parameters.

1. Heat number. The parameter characterizes the rate of heat removal from the working part of the candle. At the same time, the electrode transfers excess heat to the spark plug skirt in a timely manner, which ensures stable operation of the part. If energy is removed too quickly, scale forms on the working part of the part, which prevents normal spark breakdown. If the withdrawal is too slow, the thin electrode overheats. The process provokes the formation of glow ignition. This prevents the engine from operating normally due to detonation of the mixture or its early ignition. Under normal thermal conditions, a spark adequately breaks through the spark plugs and does not form excessive carbon deposits.
2. Spark gap. Some users know that for the engine to operate correctly, the spark gap on the spark plugs must be maintained. The working gap on VAZ spark plugs is strictly set by the manufacturer of the power plant and is necessary due to the fact that the formed electric arc has a certain strength. As the distance increases, the spark loses stability, which can lead to misfires. In the opposite case, easier starting of the engine is ensured, but when the gas is released, the electric arc current may not be enough. This is justified by the fact that each ignition coil has a certain transformation ratio, usually equal to 2000 units. This means that during the start-up of the internal combustion engine, the elements produce up to 14 kW, and during normal operation it is already 24. Consequently, failure to comply with this parameter can lead to serious disruptions in the operation of the motor.
3. Departure of the working part of the electrodes. The parameter is critical for adequate operation of the power plant. The spark plugs on the VAZ 8-valve injector, as well as for carburetor models, have electrodes strongly pushed forward. This is due to the fact that the structural parts are located in the corner of the combustion chamber, where there is no adequate ventilation. The overhang of the working part allows for better ignition of the mixture and stabilizes engine operation. If the spark plugs are mounted in a multi-valve engine, where the inserts are located in the center of the valve head, it is recommended to install spark plugs with a deep-set core - this will prevent damage to the electrodes by the piston bottom and an abundance of carbon deposits on the structural elements.
4. Number of electrodes. Initially, manufacturers position this parameter as a definite plus. When one electrode “burns out,” the spark plug switches to another, which significantly increases its service life. However, not everything is as simple as it seems at first glance. If the mixture is sprayed unevenly in the cylinder (poor ventilation of the combustion chamber), and at this moment the spark jumps to the shadowed part (the place where the exhaust remains), misfire may occur, which will lead to unstable operation of the power plant. Additionally, this fact increases the wear of the catalyst and engine oil, which is critical for VAZ cars.
5. Manufacturer. The manufacturer of the product is also an important parameter. Users recommend buying from trusted brands that have been on the market for a long time. The cost of such candles will be significant, but with proper selection and operation they will work for a long time and without significant complaints.

By adhering to the specified parameters, a car enthusiast can buy a fairly high-quality product, while saving on the frequency of car servicing and repairs.

Price issue

High-quality products always cost more. Domestic products are several times cheaper, but the quality leaves much to be desired. Therefore, it is worth buying imported candles

, which will last much longer than domestic ones. At the same time, the service life of the engine will be extended, and fuel will be consumed more economically.

Spark plugs are one of the most important parts in the ignition system of any vehicle, therefore their selection and further operation should be approached very responsibly. Depending on the type of spark plugs chosen and the quality of their installation, it will depend on how stable and, most importantly, how timely the sparking will be, which directly affects the quality of engine operation.

Let's look at the main characteristics of candles:

• Heat number. It is no coincidence that this characteristic is first on our list - focus your attention on it when buying candles. It shows the pressure in the engine cylinder at which glow ignition occurs. The indicator must correspond to the parameter specified for the engine of your car.

Advice. If you could not find spark plugs with the required heat rating, and the car urgently needs to be running, short-term use of spark plugs with a higher heat rating is acceptable. Do not allow the use of spark plugs in your car with a parameter that does not correspond to the specified one - this can lead to burnout of valves, damage to the engine cylinder head, etc.

• Gap. This is the distance between the “core” and the side electrode. If it has changed in any way, then you can restore the previous distance manually, but the best solution in this case would be to replace the spark plug (as they say, “out of harm’s way”).
• Side electrodes. The standard spark plug design has one electrode. But many modern models have several side electrodes (2,3,4 pieces). Some people mistakenly believe that the more side electrodes, the greater the number of sparks created. This is a fundamentally wrong opinion. There will still be only one spark - the process of its formation will become more stable, and accordingly, at low speeds the engine will operate more stably. Recently, spark plugs without side electrodes have gone on sale. In such models, a spark actually forms several times, at different intervals. Thus, a so-called “walking” spark is created, which ensures better ignition of the mixture. Due to the (more complex) technology used to create such candles, the price of the product is significantly higher than traditional models.

• Working temperature. It ranges from 500 to 900 degrees in any engine operating mode. If the temperature drops below the minimum limit, carbon deposits form on the spark plug insulator - it can short-circuit the spark plug gap. When the temperature rises above the maximum permissible limit, glow ignition will appear. Since this process cannot be controlled, it can lead to malfunctions of the motor.
• Thermal characteristics. It is expressed in the dependence of the insulating cone and core on the operation of the engine. Candles are divided according to this criterion into two main categories: “cold” and “hot”. The first option is used if the heating temperature of the spark plugs should be lower than the glow ignition temperature, and the engine power can be maximum. The second option is used in engines in which self-cleaning of spark plugs must be started at low temperature loads.

In the ignition circuit of the VAZ 2114, spark plugs play a central role. In fact, it is the spark plugs that carry out the control signal that comes from the ignition key when it is turned to the start position. Having received a 24 kV signal, the spark plugs generate a spark and ignite the fuel injected into the combustion chamber. Therefore, vehicle drivers pay a lot of attention to them. In order to choose the right SZ, you need to know the features of their design.

In terms of design, the spark plugs for the VAZ 2114 are no different from the SZ used in the ignition systems of other cars. The main elements of this device are:

• the body is made of metal, on the outside there is a hex head for a spark plug wrench and a threaded part for screwing into the cylinder head housing, this part absorbs 67 percent of the heat generated when the spark plug fires and transfers 91 percent of this heat to the cylinder head housing;
• an insulator made of corundum ceramics with the addition of aluminum oxide, as well as oxides of other rare metals. It is inserted into a metal case;
• thermal cone, often called the thermal cone skirt. In fact, this is the lower part of the insulator; it absorbs 21 percent of the heat released at the moment of sparking;
• a plug head is attached in the upper part of the insulator, inside it there is a contact rod mated to the head, and in the lower part there is a central electrode;
• on the lower part of the spark plug body there is a side electrode, which is located above the protruding part of the central electrode, forming a gap for the formation of a spark;
• the thrust part of the body is flat; for better tightness during installation, a sealing washer is placed on it;
• to create strength and tightness of connections inside the structure, there are ring seals and a heat-conducting glass sealant;
• To combat radio interference that occurs during sparking, a noise suppression resistor can be installed between the contact head and the central electrode.

All components of the spark plug on the VAZ 2114 play an important role, but special attention is paid to the central electrode. It must have such properties as heat resistance, high thermal conductivity, ductility and have high corrosion and erosion resistance. For this purpose, it is usually made from various nickel alloys. However, in recent years, in order to improve the efficiency of the spark plug and obtain any unique properties during its operation, this electrode began to be produced from metals such as copper, iridium, palladium, as well as with platinum deposition and silver or gold coating.
