NGK Double Platinum (Laser Platinum series) spark plugs offer extended service life and improved ignitability over conventional nickel plugs through dual platinum contact surfaces. Built as OE-equivalent replacements, they combine high-grade alumina ceramic insulation with a copper core for heat control and reliable starting. Trivalent metal plating reduces corrosion and seizing for easier installation and removal.
