Genuine GM Spark Plugs

Spark plugs are the engine components that give power to your engine's combustion process. They are simple devices that are required for your vehicle to perform reliably.

How do Spark Plugs Work in a Car Engine?

Spark plugs consist of a ceramic body that surround conductive metal such as nickel or copper. There is one spark plug for every engine cylinder you have, and their job is to pull voltage from your car battery to produce the spark that combusts the combination of fuel and oxygen inside your engine. The combustion process is what essentially runs the innerworkings of your engine.

When to Change Your Old Spark Plugs

Spark plugs can wear down after a few years. Typically, between 70,000 and 100,000 miles depending on your vehicle make and model. Spark plugs are prone to excessive use and heat which can deteriorate their charge over time. They can also become rusty and corroded which may cause engine misfires and stalls upon starting your vehicle.
