M35 Heat range plugs for standard or mild tune cars
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.
EACH PLUG SOLD INDIVIDUALLY !
Alloy Centre Electrode reduces voltage requirement as well as improving ignition performance and durability.
0.6mm Iridium Alloy Center Electrode
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.
Outer Electrode with Platinum Chip
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.
Short Type Outer Electrode (Anti-Vibration)
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.
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.
Spark Support Gap
Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.
improved Ignition Performance
New material and design improves durability, which allows for use under harder combustion conditions such as continuous high load during circuit driving or aggressive tuning. * Improper combustion condition or wrong heat range selection may cause damage to sparkplug.
Thermal Edge and Spark Support Gap help prevent carbon buildup for better ignition under various combustion conditions.
Decreased Carbon Deposits
