NGK Laser Platinum spark plug (box of 4) offers improved ignitability and longer service life versus conventional nickel plugs through laser-welded dual platinum surfaces. That slow-wearing design promotes stable idle, superior anti-fouling and better fuel efficiency. High-grade alumina ceramic and a 98% pure copper core help control temperature, while trivalent plating and triple seals improve corrosion resistance and installation reliability.
