The function and purpose of Spark Plug.

Sometimes the most important performance parts are the smallest, but they are often overlooked. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Cadillac STS spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. When one of the spark plugs does not fire when it should, the engine in your Cadillac STS will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
