Product description
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
Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life
New metal shell plating has enhanced anti-corrosion qualities
