The NGK Laser Iridium spark plug delivers a combination of long life and high ignitability suitable for OE-replacement service. A fine iridium center electrode provides exceptional wear resistance and steady spark characteristics, while high-grade alumina ceramic insulation and a copper core help regulate heat. Trivalent plating guards against corrosion and seizing, and many models include platinum on the ground electrode for balanced wear in distributorless systems.
