GMC G25 Spark Plug

Great cars and trucks like your G25 need great parts.

Your GMC dealership isn't the only place to buy genuine or original equipment quality repair parts to fix your G25. Make no mistake, you bought your G25 because you knew that you wanted performance and great value both rolled up into one automobile. GMC car, truck, or SUV owners have become used to a certain level of reliability when driving their G25 around town. When your GMC G25 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.

Sometimes the most important performance parts are the smallest, but they can be forgotten about when performing regular maintenance. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your GMC G25 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 G25 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
