There are ignition parts in your engine so small that they can be forgotten about when performing regular maintenance. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your GMC K15 spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. Should a spark plug fail to do its job, the engine in your GMC K15 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
