The NGK 4292 Laser Platinum Spark Plug - PFR5R-11 is designed to provide exceptional ignitability and extended service life. Its laser-welded dual platinum surfaces ensure a slow wear rate, delivering stable idle, superior anti-fouling, enhanced fuel efficiency, and reduced emissions. The trivalent metal plating offers outstanding anti-corrosion and anti-seizing properties, while the corrugated ribs prevent flashover. Constructed with a pure alumina silicate ceramic insulator for superior strength and better heat transfer, it also features a copper core to aid in heat removal and triple seals to prevent leakage. This makes the NGK 4292 an excellent choice for maintaining optimal engine performance.
