NGK Laser Iridium spark plug (box of 4) combines long life and strong ignitability for modern engines. A fine iridium-tipped center electrode provides exceptional durability and a stable spark; many designs include a platinum pad on the ground electrode for even wear. High-grade alumina ceramic and a copper core help control heat, while trivalent plating and triple seals assist installation and corrosion resistance.
