NGK's Laser Iridium spark plugs provide superior ignitability and long service life. The ultimate in the evolution of spark plug technology and performance from the industry leader. The iridium electrode is 25% smaller than a platinum electrode, and it’s just 1/4 the size of a conventional nickel electrode. The ultra-small diameter center electrode reduces voltage requirement and extends ignition system life. Metal shell plating has enhanced anti-corrosion qualities.
