Shop genuine Champion spark plugs for GM vehicles. Our factory-original surplus OEM plugs are supplied in new condition — exact heat range, electrode material, and thread pitch as specified by GM for your engine application.

Spark plug selection is not one-size-fits-all. Heat range determines how quickly the electrode dissipates combustion heat; incorrect heat range causes pre-ignition or carbon fouling. Our OEM Champion plugs eliminate this risk — the correct plug for your engine, every time.

Replace spark plugs as a complete set and inspect ignition wires and coils at the same time. Verify plug specifications against your engine RPO code before ordering.
