Specifications 0.6mm Iridium Alloy Center Electrode reduces voltage requirement and improves ignition performance as well as durability.

The Outer Electrode incorporates a square platinum chip which boosts ignition performance and improves durability when combined with the iridium center electrode.

The Outer Electrode features a tapered shape and shortened tip design while maintaining the necessary space for proper ignition.

Short Type Outer Electrode (Anti-Vibration) The outer electrode has been engineered with the ideal shape and shortened to decrease weight for resistance against vibration.

This design improves the longevity of the outer electrode.

Thermal Edge After long idling or various combustion conditions, carbon buildup can occur causing misfires.

The Thermal Edge of the ceramic insulator will discharge to help decrease carbon deposits.

Discharges will occur in the Spark Support Gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
