Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. If one of the spark plugs wears out, the engine in your GMC Sierra 2500 HD Classic will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

Good products, great prices, the best people.
