Description NGK PLKR7A Laser Platinum Plugs Product Description: The NGK PLKR7A is a Laser Platinum spark plug designed for high performance and durability, featuring a laser-welded platinum tip on the center electrode and a platinum chip on the ground electrode for slow wear, stable idle, and consistent ignition. Key features include superior anti-corrosion/anti-seize trivalent metal plating, a pure alumina ceramic insulator for heat transfer, a copper core for heat removal, and corrugated ribs to prevent flashover, ensuring improved fuel efficiency, lower emissions, and better throttle response. Product Features: Dual Platinum Design: Platinum on the center and ground electrodes provides high erosion resistance and a long service life. Superior Ignitability: Laser-welded fine wire electrodes ensure a consistent spark and efficient combustion. Anti-Corrosion: Trivalent metal plating offers excellent resistance to corrosion and seizing, making installation and removal easier.
