 Specifications: 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 durability, and when combined with the iridium center electrode boosts ignition performance.
- 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.
- Heat Range: 9
