The NGK Laser Iridium High Ignitability spark plug combines advanced tip technology with OE-equivalent durability to deliver quick starts and consistent spark performance. Iridium-tipped center electrodes and a raised platinum pad or fine wire ground tip promote even wear in distributorless systems while high-grade alumina ceramic and a 98% pure copper core reduce overheating; trivalent plating helps resist corrosion and seizing.
