HKS SUPER FIRE RACING SPARK PLUG M40XL

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, and anti-carbon build-up. The Iridium alloy is used because of its durability and reliability. On an average plug, a narrow core typically shortens the life span of a plug but with the intense durability of iridium, there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high levels of compression and minor knocking without any deterioration. A nickel coating on the housing also prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in colder to heat ranges of 7 and up and specifically for rotary, heat ranges of 9 and up are offered.

Features Include:

  • 0.6mm Iridium Alloy Center Electrodereduces 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. *M Series is recommended for reliable ignition, durability, and anti-carbon buildup under high load.
