NGK Laser Platinum spark plugs use dual welded platinum surfaces to extend service life and maintain high ignitability compared to conventional nickel plugs. They promote stable idling, reduced fouling and improved fuel efficiency for OE replacements. High-grade alumina ceramic and a copper core control heat while trivalent plating resists corrosion and seizing for reliable starts.
