Toyota 86 / Subaru BRZ
M45HL - Naturally Aspirated
M50HL - Forced Induction (Supercharged, Turbo)
- Set of 4
- Thread Size: 12x 26.5mm
- Wrench Size: 14mm
- 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.
- Thermal Edge
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.
- Spark Support Gap
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.
