- The ultimate in the evolution of spark plug technology and performance from an 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
- Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
- Metal shell plating has enhanced anti corrosion qualities
