Ignitionability, durability, anti-insulation are all reinforced. HKS has made the best plug for both tuning engines and stock engines.
FEATURES
- 0.6mm Iridium Alloy Center Electrode
Iridium alloy center electrode reduces voltage requirement and improves ignition performance and durability.
- Outer Electrode with Platinum Chip
The outer electrode incorporates a square platinum chip which improves durability, and combining 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.
After long idling or under various combustion conditions, carbon buildup can occur causing misfires. The thermal edge of the ceramic insulator discharges to help decrease carbon deposits.
Discharge occurs in the spark support gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
