Spark Plugs

Fouled spark plugs are the likely cause of engine misfiring. Fouled spark plugs are often caused by parking a vehicle for long periods (weeks or months), frequently allowing a vehicle to sit idle with the engine running for 15 minutes or longer or driving numerous short trips in a short period of time. You can often clean dirty spark plugs, but if you find that doesn’t alleviate the problem, they should be replaced. For genuine GM parts at wholesale prices or below, shop our online catalog for the right spark plugs by choosing the Year, Make and Model of your vehicle below.
