Obviously, you bought your G25 because you understood you would be getting performance and rugged design both rolled up into one vehicle. While it's not hard to buy replacement parts for GMC vehicles, these days only the highest quality are required to repair your car or truck. It's not all the time that you realize that you have to buy a replacement Spark Plug for your car or truck.

Why Spark Plug replacement is so important.

There are ignition parts in your engine so small that 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 G25 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 G25 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
