The NGK Laser Platinum spark plug combines extended service life with improved ignitability compared to conventional nickel plugs. Dual laser-welded platinum surfaces slow wear for stable idle, better anti-fouling and improved fuel efficiency. NGK uses a high-grade alumina silicate insulator and a copper core to prevent overheating and maintain reliable starts. Trivalent plating protects against corrosion and seizing, and many plugs include a platinum pad on the ground electrode for even wear.
