NGK IRIDIUM IX SPARK PLUGS

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 a quarter of the size. Ultra-small diameter center electrode reduces voltage requirement and extends ignition system life. The new metal shell plating has enhanced anticorrosion qualities, making the NGK Iridium IX spark plug the leader. Ultra-Fine center electrode designed to reduce the voltage requirement and ensure maximum durability.
