Anyone who owns a GMC knows that when it comes to repairing their vehicle only the most superior replacement parts will do. You purchased your LI3500 because its reliability and longevity struck a chord inside you; so why would you be okay with second best when it comes to the highest quality auto parts? When your GMC LI3500 rolled off the assembly line, it was destined for a person with discerning taste who prioritizes trusted quality in their automobile. It's not a regular occurrence that you find yourself in need of a replacement Spark Plug to repair your vehicle.
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 GMC LI3500 spark plug. 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 LI3500 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
