HKS SUPER FIRE RACING SPARK PLUG " RACE " M45HL
PLUGS SOLD IN SINGLES
HKS SUPER FIRE RACING (M SERIES) PLUG TYPE HERE
Improved ignition performance, durability and anticarbon build-up. The Ultimate sparkplug for increasing performance of tuned or stock engines.
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.
Performance and Efficiency
Increased Ignition Performance
Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.
M45HL heat range NGK9
M Series is recommended for reliable ignition, durability and anti-carbon buildup under high load.
