NGK Laser Iridium High Ignitability spark plugs are engineered specifically for OE applications to provide the ultimate combination of performance and longevity. This Double Fine Electrode (DFE) plug features a laser-welded iridium-tipped center electrode and a raised platinum pad on the ground electrode. This design ensures even wear and superior spark performance, making it the ideal choice for modern distributorless ignition systems where durability and reliable ignitability are critical.

Built to withstand extreme conditions, these plugs utilize a high-grade pure alumina silicate ceramic insulator for superior dielectric strength and heat transfer. The 98% pure copper core aids in heat removal to prevent overheating, while trivalent metal plating provides long-term resistance to corrosion and seizing in the cylinder head.
