Features:

0.6mm Iridium Alloy Center Electrode

Iridium Alloy Center Electrode reduces voltage requirement as well as improving ignition performance and durability

Outer Electrode with Platinum Chip

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

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

Short Type Outer Electrode (Anti-Vibration)

The outer electrode has been shortened and engineered with the ideal shape to decrease weight for resistance against vibration. This anti-vibration design improves 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

Spark Support Gap

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.
