HKS M-Series Super Fire Racing spark plugs are high-performance iridium plugs designed to handle advanced levels of tuning and provide improved ignition performance, durability & anti-carbon build-up.
Features & Specs:
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 durability, and when combined with the iridium center electrode boosts ignition performance
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 the 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 the insulator and the base of the outer electrode) to help prevent carbon buildup. *These plugs come pre-gapped to 0.028" from HKS, reducing the gap down to 0.022" for maximum performance applications may be required..
Important Note: This product is not necessarily vehicle specific. Spark plugs are compatible with a wide range of different applications and therefore they are displayed on our site regardless of your vehicle type. Please review the specifications and verify vehicle compatibility prior to placing your order with us. These are considered "off-road" racing plugs, and therefore do not come with a warranty, other than being DOA. (Dead on arrival)
