The NGK Laser Iridium High Ignitability spark plug provides OE-grade ignitability and extended service life for today’s engines. It’s built to improve ignition reliability and throttle response compared with conventional plugs. An iridium-tipped fine-wire center electrode offers exceptional durability; many High Ignitability variants use a raised platinum pad or platinum fine-wire on the ground electrode for even wear. High-grade alumina ceramic, a 98% copper core, triple seals and trivalent plating support heat control and corrosion resistance.
