What brand of spark plugs does GM use?
GM primarily uses ACDelco spark plugs, the GM Genuine Parts brand, as the standard equipment and replacement plugs across most of its vehicles.
ACDelco: The official GM spark plug brand
ACDelco is GM's in-house OE and aftermarket parts division. Spark plugs under the GM Genuine Parts label are designed to meet GM's ignition system specifications, ensuring compatibility, performance, and warranty coverage across GM vehicles.
Range of plug designs
The ACDelco line includes copper-core, platinum, and iridium plugs, with variations tailored to different GM engines and service intervals. The exact design and heat range are specified by GM for each engine family.
- Copper-core spark plugs (affordable, adequate performance for older engines)
- Platinum spark plugs (longer life, common in many modern engines)
- Iridium spark plugs (high durability and efficiency for newer engines)
When replacing, the correct plug type, heat range, and gap are essential, and GM's official parts catalog or your dealer can confirm the exact specification for your vehicle.
Regional variations and exceptions
In most regions, GM's OE spark plugs are supplied by ACDelco. However, some markets or specific collaboration models may have used spark plugs from other brands as original equipment. Always verify the recommended part for your vehicle in the GM Genuine Parts catalog or with a GM dealer.
How to verify the right spark plug for your GM vehicle
Check the vehicle's owner's manual or the GM Genuine Parts catalog for the exact spark plug part number, heat range, and gap. Replacing with the correct plug helps avoid misfires and preserves warranty and performance.
Summary
GM's primary spark plug brand is ACDelco, sold under the GM Genuine Parts umbrella. This brand is used for most GM vehicles as original equipment and in replacements. Always confirm the specific plug type for your engine in the official GM parts catalog or with your GM dealer.
