The NGK Laser Iridium spark plug is an OE-grade replacement offering long life and consistent ignition for modern engines. Iridium fine-wire center electrodes give superior durability compared with platinum, while high-grade alumina ceramic and a 98% copper core control heat and support reliable starts. Many Laser Iridium variants add a platinum ground pad, trivalent plating and triple seals for corrosion resistance and leak prevention.
