The NGK Laser Platinum double-platinum spark plug features dual platinum surfaces for slower wear and longer life, providing stable idling, reduced fouling and improved fuel economy. Built as an OE-equivalent replacement, it pairs high-grade alumina ceramic insulation with a copper core for effective heat management. Trivalent plating helps guard against corrosion and seizing, simplifying installation and extending usable service intervals.
