The NGK Laser Iridium High Ignitability spark plug is an OE-equivalent option tuned for stronger spark performance and long life. It’s intended for engines requiring high ignitability and consistent combustion under varied conditions. A fine-wire iridium center electrode provides durability well above platinum; many models include a raised platinum pad or fine-wire tip on the ground electrode to promote even wear. High-grade alumina ceramic, a 98% copper core, triple seals and trivalent plating help control heat and resist corrosion.
