The NGK Laser Platinum double-platinum spark plug offers enhanced ignitability and extended service life compared with conventional nickel plugs. Laser-welded dual platinum surfaces resist wear for stable idling, improved anti-fouling, better fuel efficiency and lower emissions. Built to OE standards, the plugs use high-grade alumina ceramic insulation and a 98% copper core to prevent overheating, plus trivalent plating to reduce corrosion and seizing.
