Spark Plugs

Refine Results

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.

Signs That You Need to Replace Your Spark Plugs

Spark plugs can last up to 100,000 miles before showing signs that they require replacement. If your spark plugs need to be replaced, your vehicle may show signs such as:

  • Engine misfiring and sputtering
  • Engine failure at start
  • Lack of acceleration
  • Receiving lower fuel mileage
  • Check engine light turns on
  • If you've recently encountered any of these engine complications, seek a professional inspection from your nearby GM technician. Then, order your new spark plugs online and save money.
