HKS Mi-Series Super Fire Racing Spark Plug -  HKS M45HL - Grade 9

Note - Price is for 1 single spark plug

HKS Mi-Series Long Reach 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.

HKS Mi Series Spark Plug Features:

• 0.6mm Iridium Alloy Centre Electrode. Iridium 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 centre 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 longevity of the outer electrode.
  
• Thermal Edge: After long idling or various combustion conditions carbon build up 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 build up.
  
• Long Reach
• Heat Range: 9
