GM Spark Plugs

During vehicle start-ups, the distributor sends an energy surge along the wire and into the GM Spark Plug.

Positioned at the top of your vehicle's cylinder head, the Car Part plays an important role in the fuel combustion process.

Upon exiting the Genuine Part, the current's voltage is high enough to jump the gap and burn the air-fuel mixture sitting in the combustion chamber.

This GM Spark Plug forces electricity to arc across a gap and create the spark needed to ignite the air-fuel mixture.
