Details of this specific product are as follows:

0.6mm Iridium Alloy Centre Electrode:
Iridium Alloy Centre 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 centre 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 build up 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 build up.

Increased Ignition Performance:
Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.

Improved Durability:
New material and design improves durability, which allows for use under hard combustion conditions like continuous high load during circuit driving or aggressive tuning.

Decreased Carbon Deposits:
Thermal Edge and Spark Support Gap help prevent carbon build up for better ignition under various combustion conditions.
