Great cars and trucks like your EC251 need great parts.

GMC car, truck, or SUV owners have become used to a certain level of reliability when driving their EC251 around town. Auto enthusiasts appreciate the a brand you can trust built into each GMC, and understand that only the best replacement EC251 parts will suffice when repairs are needed. You picked your EC251 because its dependability and longevity agreed with your nature; so why would you settle for anything but the best when it comes to superior quality auto parts? The vehicle in your driveway is head and shoulders above the rest compared to all the other vehicles these days.

What Spark Plug does for your vehicle.

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 EC251 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 EC251 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.
