OEM GM Spark Plugs

When you need your engine to fire, you need the spark plug to deliver the spark that causes the combustion. These are high voltage plugs that can reach volts of 40,000 or more because they have to arc across a gap in order to start the explosion.

A spark plug is required on every cylinder of your engine, so if an Ion or LaCrosse have six cylinders, they will have six spark plugs. Likewise, if a Tahoe has eight cylinders, it will have eight spark plugs. Spark plugs have to be tough because they are subject to high heat, a lot of electricity and extreme pressure within the cylinder.

When you replace the spark plugs, a genuine OEM GM spark plug will be manufactured to withstand the specific needs of your GM vehicle, so they will be optimized for performance. A generic spark plug may not have the lifespan of an OEM plug because they are not built to take the heat.

You will need to change the spark plugs in your vehicle at some point. They can get a buildup that clogs the gap, which causes them to lose their spark. This means that your engine will run roughly and cough and sputter.
