GM Spark Plugs

One of the smallest parts of your vehicle happens to be one of the most important components of the ignition system. The spark plugs help to contribute to the operation of your GM vehicle and help create the ignition needed for the combustion process to take place. Spark plugs emit little bolts of electricity that help create this. When this happens, the movement of your pistons are set into motion and help your vehicle burn the air-fuel mixture inside of your car. Once you turn the key in the ignition, the spark plugs help the car to stay powered up. Engine health can be directly linked to spark plug performance, which is why having OEM spark plugs under the hood is so important. Though they are parts that can withstand a large amount of heat and pressure, checking their condition on a regular basis is a good idea. Knowing when you might need to replace spark plugs is important so that you can make replacements early on and be proactive. Of course, a check engine light can be a sign that you might need to replace something under the hood of your car. Loud and jittery sounds during idling can also be symptoms of failing spark plugs.
