Which NGK spark plugs are suitable for VAZ 2114

Every gasoline engine vehicle requires spark plugs to operate. Plugs, along with fuel, ensure the reliability and uniformity of operation of the entire power plant; if the spark plugs reach their service life, various interruptions in the operation of the engine may occur, including stopping.

This article talks about the spark plugs used in the VAZ 2114 car, namely about their timing and replacement methods, gaps and brands that are perfect for the engine of the “fourteenth” Lada model.

After studying this article you will find a lot of interesting and useful information about choosing spark plugs for your car.

What is a candle for?

Spark plugs in a car are one of the main elements of the ignition system. It is the spark plugs that ignite the fuel mixture while it is being compressed by the piston. When the fuel in the combustion chamber is compressed, the spark plug produces a spark, thereby igniting the mixture.

The spark on the spark plug appears under the influence of high voltage generated from the ignition module. The voltage on the spark plug can reach several tens of kilovolts, which is a lot. For example, in a household outlet there is only 220V. Therefore, due to the high voltage, touching high-voltage wires while the car engine is running is PROHIBITED.

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.

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;

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.

Gap on spark plugs VAZ 2114

One of the most important parameters in a spark plug is the gap between its contacts. This gap affects the formation of a spark at the contacts; the smaller the gap, the stronger and faster the spark; the larger, the weaker.

On VAZ 2114 engines, spark plugs must have a gap of 1 mm. This gap is optimal for proper and reliable operation of the engine.

How to choose good candles

When choosing spark plugs for 2114 8 valve injector, you should be guided by the following important points:

1. Electrode homogeneity. A high-quality branded candle, even a budget-class one, will have electrodes with a clean, single-color surface. The presence of any stains on it should immediately cause refusal of the purchase.
2. Manufacturer. It is best to give preference to time-tested products. Thus, spark plugs from Finwhale, Champion, and Bosch Platin receive good reviews from car enthusiasts.
3. Color and size of electrodes. The highest quality candles have the thinnest electrodes (they are usually made of alloys of gold, silver, palladium, platinum or are coated with these metals). Spark plugs with the usual thick electrodes are more budget-friendly and have a shorter service life and lower-quality spark production.

One of the most objective methods of identifying a fake is to study its value. As already mentioned, the electrodes of good spark plugs contain rare earth or even precious metals, which makes their high price obvious. That is why you should not purchase such products, the cost of which does not differ from the cost of ordinary candles, because in the vast majority of cases they will turn out to be fake.
