GMC EF350 Spark Plug

Great cars and trucks like your EF350 need great parts.

Obviously, you didn't buy your EF350 unless you understood you would be getting horsepower and rugged design both impeccably combined into one car, truck, or SUV. While it's not hard to buy replacement parts for GMC vehicles, these days only the absolute best are required to fix your car or truck. The vehicle in your driveway is head and shoulders above the rest compared to all the other cars, trucks, and SUVs these days. You purchased your EF350 because its reliability and trusted quality struck a chord inside you; so why would you be okay with anything but the best when it comes to superior quality auto parts?

What Spark Plug does for your vehicle.

There are ignition parts in your engine so small that they aren't considered when there's a performance problem. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC EF350 spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. Should a spark plug fail to do its job, the engine in your GMC EF350 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.

You've tried the rest, now try the best.
