Spark Plugs
Spark plugs are the device located in each of your GM's engine cylinders. They are the mechanism that kicks off the combustion process when your engine valves and pistons push together fuel and oxygen.
Why Genuine GM Spark Plugs are Important for Your Car, Truck or SUV
Spark plugs are made of conductive metals like nickel, copper, or aluminum oxide ceramic with a steel wire shell that can withstand high temperatures. They draw power from the car battery to create the sparks needed for combustion. With the many varieties of spark plugs on today's auto parts, having the recommended ones for your specific model engine is essential. We have conveniently created an algorithm that aligns you with the best spark plug options for your make, year, and model.
