ACDelco GM Original Equipment Iridium Spark Plug

ACDelco GM Original Equipment Iridium Spark Plugs are the latest in spark plug technology and an exact replacement for your vehicle's original components, designed, engineered, and tested to rigorous standards, and backed by General Motors. Iridium composition provides a high melting point and great strength, ensuring excellent wear resistance and durability.

These OE parts are the true components installed during the production or validated by General Motors for GM vehicles. Some may have previously been known as GM Genuine Parts (OE) or ACDelco Professional. Iridium offers excellent engine idle stability and smooth performance, allowing for small, efficient electrode designs that enable reliable cold starting and quick acceleration.

The iridium fine-wire electrode helps burn away carbon deposits on the tip of the plug as they form, while the one-piece suppressor seal blocks radio frequencies that can affect vehicle electronics. The suppressor seal also meters spark energy for long electrode life and helps prevent combustion leakage.

GM engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle, ensuring they work seamlessly with your vehicle's safety systems. Aftermarket replacement parts may not meet the same OE safety regulations, depending on the part type.

To integrate new materials and technologies, GM regularly updates production and service part designs. ACDelco GM Original Equipment parts are the true OE parts you can trust to maintain the performance and safety of your GM vehicle.
