GMC C25 Spark Plug

Your C25 is a prized possession.

Your GMC dealership isn't the only place to locate trusted parts to repair your C25. You bought your C25 because its reliability and trusted quality agreed with your nature; so why would you be okay with anything but the best when it comes to the highest quality auto parts? GMC vehicle drivers have become used to a certain level of reliability when driving their C25 around town. Auto enthusiasts appreciate the strong looks built into each GMC, and know that only the best repair C25 parts will suffice when repairs are needed.

What Spark Plug does for 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 creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC C25 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 C25 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.

The best parts are right around the corner.
