Some engine parts are tucked away out of sight, so they aren't considered when there's a performance problem. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Buick GS 400 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 Buick GS 400 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
