Spark plugs are small but mighty and are a vital part of your car’s engine. They are a small dynamo that supplies a spark that powers up a car’s combustion.

Pistons inside the car engine will then begin to move, and your vehicle will power up. Your vehicle will then maintain the power to burn the compressed air-fuel mixture. Spark plugs are very strong and durable as they can cope with high temperatures as well as pressure from the cylinders. They can also burn off any fuel deposits or contaminants that come from the engine.

Spark plugs are generally a long-lasting component, but they will need to be changed occasionally. It’s a good idea to replace your spark plug once you’ve driven between 30,000 and 100,000 miles. This will vary slightly depending on what type of vehicle you own. It’s a good idea to check the owner’s manual for advice; many cars require their spark plugs to be changed once a year.

After years of use, spark plugs will eventually stop working effectively and need replacing. During its life span, a spark plug will go through extremes of temperatures. They are made of hardwearing, durable materials so that they can withstand extreme heat. 

Although spark plugs last for years, they do eventually wear out. One of the main reasons spark plugs fail is that deposits build up on their surface. This is often as a result of air and fuel mixing which can cause fuel pre-ignition. If this happens, your car will start to have problems as your vehicle’s power supply will be unpredictable, which can cause issues with starting your vehicle.

Another reason that spark plugs fail is that the gap that the spark has to jump becomes wider. In regular use, the space in which the spark travels need to be wide enough to provide effective combustion. As a spark plug ages, it becomes worn, and the gap becomes more extensive. The gap may widen because of exposure to extremes in temperatures as well as the build-up of debris and daily wear and tear. If the gap becomes too wide, your spark plug will fail to start your vehicle and will need to be replaced.
