GMC C25 Suburban Spark Plug

Your C25 Suburban is a prized possession.

Your GMC dealership isn't the only place to locate the best replacement parts for your C25 Suburban. Anyone who owns a GMC knows that when it comes to maintaining their vehicle only the absolute best replacement parts will do. Make no mistake, you bought your C25 Suburban because you knew that you wanted performance and great value both rolled up into one vehicle. When your GMC C25 Suburban left the factory, it was destined for a driver who values longevity in their automobile.

Why Spark Plug replacement is so important.

Some engine parts are tucked away out of sight, so they can be forgotten about when performing regular maintenance. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC C25 Suburban spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. When one of the spark plugs does not fire when it should, the engine in your GMC C25 Suburban will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

The best parts are right around the corner.
