GMC K15 Spark Plug

Keeping your K15 in top shape is your top priority.

Select Your VehicleWhile it may not be difficult to find replacement parts for GMC vehicles, these days only the absolute best are required to maintain your car or truck. Anyone who drives a GMC knows that when it comes to maintaining their vehicle only the most superior replacement parts will do. Obviously, you bought your K15 because you knew that you wanted horsepower and rugged design both rolled up into one automobile. When your GMC K15 left the factory, it was destined for a driver who prioritizes longevity in their automobile.

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

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 K15 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. Should a spark plug fail to do its job, the engine in your GMC K15 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.

The experience this company has to provide.
