Changing the car spark plugs makes the performance of the vehicle at a high level. The main function of a spark plug is fuel consumption. If you intend to reduce fuel costs and pollution, you should definitely consider using a suitable spark plug and replacing the current product in the car.

What is a car spark plug?

Vehicles that use gasoline or gas are actually flammable. Such vehicles need to burn fuel to move. The spark plug of the car causes the ignition to take place and the fuel becomes the energy needed for movement. When you start the car, the spark plug will transfer the necessary energy.
Changing spark plugs is not difficult. But you must be aware of the exact time of replacement. Each candle has a useful life. The standard life span of a car spark plug is 50,000 kilometers. But some candles may have a longer life. If you replace the spark plug prematurely, your cost will only increase and the process of replacing the spark plug will be difficult.

The importance of maintenance of car spark plugs

If you care about the health of the car, you should be concerned about the health of the engine components. The spark plug is one of the important parts of the car engine, whose performance will directly affect the performance of the car as well as the consumption of the car.
There is a gap in the spark plug head where the electrode is placed. Over time, these electrodes generate a lot of sparks. All these sparks cause a change in the physical nature of the candle.
Any mechanical product will get tarnished or damaged over time. From the cooler to the door hinge, they all have a useful life. Car spark plugs also have a useful life. One of the ways to ensure the health of a car spark plug is to know its useful life, which is announced to you when you buy or replace it.
If the car’s spark plug has a problem, the engine will have problems over time. It is also possible that the failure of the spark plug is due to the failure of the engine and the combustion process. In this way, you will be able to treat the engine in the future.

How to ensure the health of the car spark plug?

There are different ways to answer this question. As we said, one of the basic ways is to know the useful life of the candle. If your engine has a problem, the amount of fuel consumption has changed, or you feel that the production pollution of the car has increased, you should open and check the spark plug of the car and make sure of the health of the spark plug of the car. After opening the candle, you should check its color and shape. In most cases, you will encounter the following forms:

1- If your candle is healthy, its head will have a very light gray color. The new candle that you buy has this color. If you still have ignition problems in the engine with these specifications, the problem is probably from somewhere else, such as the spark plug wire.

2- Look for signs and carbon footprints. Sometimes the fuel entering the engine may be too rich. It means that the amount of fuel is more than air. This will cause the candle to fail. The sign of such an event is a series of dark and black spots and soot. Clean the spark plug and take the car to a mechanic to find out why the fuel is too rich.

3- Identify the black spots. Sometimes, the combustion process may not take place properly. Because of this, a series of black spots will appear on the candle. A part of the car, such as the timing belt, may have a problem. Also, if this problem continues, the valve of the car will have a problem. Sometimes a spark plug is not suitable for a car and does not have the ability to withstand the necessary heat.

4- Look for the candle to be wet. Your candle may be wet. This wetness is due to an oil leak. The oil may have come into contact with the spark plug through various holes. If the spark plug is dry, the problem is carbon, but if it is wet, it is a sign of contact with excess oil, which is the problem of the car itself. Oil leakage will also cause deposits. If you encounter a series of white deposits, your problem may be an oil leak.

5- Look for burns and damage. If the engine overheats, the spark plug will also be damaged. Check the spark plug head and see if it is burnt or broken and damaged. Due to chemical interactions, it is possible that the tip of the candle will be eaten and its size will be smaller.

6- Maybe the candle is old. Obsolescence is one of the forms of car spark plug failure. Check the screws, maybe your spark plug has a new and strange shape or it is obvious that it is old. Corrosion, chipping and rusting are all possible under these conditions.
