Since a car engine is an internal combustion engine that runs on gasoline, the gasoline must be ignited inside it in order for it to work and move the car, so engines contain spark plugs whose function is to ignite the air-fuel mixture inside the cylinders in order for the engine to rotate.
Spark plugs are very important in any gasoline engine; because it simply will not work without them, or if they are not in good condition, the engine will not work well or not at all, so it is necessary to check them sometimes or with every oil change to make sure they are usable.
Because the spark plugs affect the work of the engine a lot, it is necessary to inspect and check them when buying a used car, but if you want peace of mind, Motorgy offers you used cars for sale in Kuwait fully inspected and at the best prices to buy your dream car, and you are happy every time you drive it.

What are the causes of spark plugs damages?
The following are the most important reasons that lead to damage to the spark plugs in your car's engine:
Wear and tear
Since they are inside the cylinders during the combustion process, their spark ignition heads wear out over time due to heat and frequent use, and the more the ignition heads wear out, the weaker their performance will be, and they will continue to wear out until they are completely worn out and need a new set of spark plugs.
Carbon buildup
If your car's engine is very rich in fuel, meaning that the amount of fuel is more than the air in the mixture that will enter the engine, this will cause carbon buildup on the spark plugs and prevent them from doing their job properly, and here you can clean and decarbonize them if they are usable, but if they are old, you must change them immediately.
Oil buildup
Damaged piston rings that prevent cylinder pressure from exiting can allow engine oil to enter the combustion chamber, causing oil to collect on the spark plugs, and this oil will prevent them from releasing the correct spark to ignite the air-fuel mixture, and this will lead to poor engine performance or possibly stop working if the oil covers the spark plugs.

Overheating
Overheating the engine can cause the bushings to wear out more quickly, often due to issues such as poor quality gasoline, issues with the cooling system, or too little fuel in the cylinder.
Incorrect installation
If the spark plugs are not installed correctly, the edges of their gears will not be aligned with the cylinder wall, and this will result in several issues such as engine pressure escape, damage to the cylinder gears and loss of the ability to generate a correct spark from the correct distance or position, and this will negatively affect not only the performance of the engine, but also the engine gears on which the bushings are installed, and you will need to turn the gears to get them back to their proper condition.
Using the wrong spark plugs for the engine
Every car engine must use the appropriate spark plugs that are recommended by the car manufacturer, and the information about the spark plugs for the engine is found in the owner's manual in the car, or you can contact the dealership and get the correct information about the type of spark plugs that should be used and when to change them.

Negligence
Every car driver must perform regular maintenance on his car and inspect it constantly and change the oil, filters and brakes, in addition to the pads, as the pads have a lifespan to keep them working without issues, and lack of maintenance or neglect will contribute to damaging the spark plugs and possibly endangering the engine if they are left corroded for a long period of time.
