The NGK Double Platinum spark plug features laser-welded dual platinum surfaces for slow wear and extended service life, making it an ideal OE-equivalent upgrade. Dual platinum tips maintain stable idling, resist fouling and support improved fuel efficiency and lower emissions. The plug also uses high-grade alumina ceramic and a copper core for heat control, plus trivalent plating to help prevent corrosion and ease installation and removal.
