GMC C15 Spark Plug

You enjoy taking care of your C15.

It's not all the time that you find yourself in need of a replacement Spark Plug to fix your vehicle. Make no mistake, you bought your C15 because you knew that you wanted horsepower and great value both impeccably combined into one automobile. Anyone who operates a GMC knows that when it comes to repairing their vehicle only the highest quality replacement parts will do. Your GMC dealership isn't the only place to buy trusted parts to repair your C15.

Don't go too long without fixing your Spark Plug... here's why.

Sometimes the most important performance parts are the smallest, but 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 C15 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 C15 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.

The best parts are right around the corner.
