The NGK Laser Iridium spark plug delivers a balance of longevity and reliable ignitability for OE-style applications. A fine iridium-tipped center electrode provides enhanced durability—much harder than platinum—while high-grade alumina ceramic insulation and a 98% copper core aid heat dissipation and prevent overheating. Trivalent plating and triple seals reduce corrosion and leakage, offering a dependable OE-equivalent replacement for modern engines.
