Spark Plugs

The job of the spark plugs is to deliver electric current from the ignition system to the combustion chamber. In other words, they provide the spark for lighting the fuel that helps your engine to start. They are an important part of your Chevy's performance. Although spark plugs generally last a long time (around 20,000 to 40,000 miles) it is good to check them and make sure they are working properly. Sometimes they may just need to be cleaned. Some systems of bad of failing spark plugs might be slow acceleration, poor fuel economy, engine misfiring or difficulty in starting your engine. Spark plugs are made of different materials and the type of the material might determine how long they last. The types of materials might be copper, platinum and iridium. You should refer to the Chevrolet manufacturer's instructions regarding when to change them.
