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 its just 1/4 the size of a conventional nickel electrode. Ultra-small-diameter center electrode reduces voltage requirement and extends ignition system life. New metal shell plating has enhanced anticorrosion qualities.
