The function and purpose of Spark Plug.

There are ignition parts in your engine so small that 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 K25 Suburban spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. If one of the spark plugs wears out, the engine in your GMC K25 Suburban will not turn as hard; reducing power and gas mileage while increasing harmful emissions.

Good products, great prices, the best people.
