Spark Plugs

Like tiny bolts of lightning, your spark plugs generate electricity that is vital for your engine to start. They're a small part of your GM vehicle's ignition system, but they serve an important purpose. The job of giving your engine the electricity to run as it should is one of the reasons why your spark plugs are so important. They ignite the air and fuel mixture inside of your vehicle to allow for combustion at the perfect time. Your engine could fail to start or misfire if there are issues with the spark plugs. While they are made to last and handle the heat, they are not indestructible, and over time, may wear out. If that's the case, you'll want to replace them right away, so you don't have issues starting your engine. Suggestions from most manufacturers suggest replacing the spark plugs at about every 30,000 miles. You can refer to the manual for your GM vehicle for their recommendation.
