The NGK 90654 Laser Iridium Spark Plug SILZKFR8E7S is engineered to provide exceptional ignitability and durability. It features a fine wire iridium-tipped center electrode and a fine wire platinum-tipped ground electrode, designed for a slow wear rate that maintains stable idle, superior anti-fouling capabilities, enhanced fuel efficiency, and reduced emissions. The plug incorporates trivalent metal plating to resist corrosion and seizing, while corrugated ribs prevent flashover across a wide range of engine conditions. Its pure alumina silicate ceramic insulator ensures robust strength and efficient heat transfer, complemented by a copper core that facilitates effective heat dissipation. Furthermore, triple seals on the plug prevent leakage, guaranteeing consistent performance and longevity in various driving environments.
