ACDelco GM Original Equipment Iridium Spark Plugs are the true OE parts installed during the production of or validated by General Motors for GM vehicles. These premium aftermarket replacement spark plugs are designed, engineered, and tested to rigorous standards, and are backed by General Motors.

Iridium composition provides a high melting point and great strength, ensuring excellent wear resistance and durability. Iridium allows for small, efficient electrode designs that contribute to 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 and meters spark energy for long electrode life, preventing combustion leakage.

Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional. ACDelco GM Original Equipment parts are the true OE parts, designed and validated by GM Engineers specifically for Chevrolet, Buick, GMC, or Cadillac vehicles. GM regularly updates production and service part designs to integrate new materials and technologies, ensuring the highest quality and performance.
