The NGK Laser Platinum single-platinum spark plug offers improved ignitability and extended service life as an OE-equivalent replacement and is recommended for rotary engines. A fine wire platinum center electrode supports stable idling and reduced fouling while high-grade alumina ceramic and a copper core help control heat. Trivalent plating resists corrosion and seizing, making the plug easier to install and remove.
