HKS Super Fire Racing M40i Spark Plugs50003-M35-I HEAT RANGE 7
Spark plugs become a key factor in clean and complete combustion in any petrol engine. Clean and complete combustion is paramount in performance tuning as the power produced is directly related to the force of the combustion. HKS offers a large range of spark plugs to accommodate a wide range of vehicles in varying different states of tune.
Improved ignition performance, durability and anti-carbon build-up. The Ultimate spark plug for increasing performance of tuned or stock engines.
Specifications
0.6mm Iridium Alloy Center Electrode
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 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.
