What Spark Plug does for your vehicle.

Sometimes the most important performance parts are the smallest, but they aren't considered when there's a performance problem. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC C15 Suburban spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. When one of the spark plugs does not fire when it should, the engine in your GMC C15 Suburban will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
