HKS Iridium Super Fire Racing Spark Plug Nissan GTR R35 VR38DETT Two Steps Colder 50003-M50HL

HKS Iridium Spark Plugs (50003-M50HL) Super Fire Racing Spark Plug, HL Type Heat Range : NGK # 10, Thread Size: 12mm × 26.5mm, Wrench Size: 14mm

HKS is the first to release the high heat range tuning spark plug M12 long reach HEX size 14 for 86, BRZ and GT-R to the market.

FEATURES

• New HKS M50HL is the same as NGK 10. It's for a high tuning vehicles.
• Two Steps Colder than stock for Nissan GT-R R35 with stock's heat range of NGK 8.
• One Step Colder Colder than stock for Toyota 86 / Subaru BRZ with stock heat range of  NGK 9.
• Reinforced by making the outer electrode bigger. Also could have a steady ignition and ignition speed at a high load and high RPM by putting the center electrode in the middle of the spark plug.
• Improved the anti-taint property by making thermal edge to prevent the carbon buildup which occurs for the tuned engines.

Specifications:

• 0.6mm Iridium Alloy Center Electrode
  Iridium alloy center electrode reduces voltage requirement and improves ignition performance and durability.
  
  
• Outer Electrode with Platinum Chip
  The outer electrode incorporates a square platinum chip which improves durability, and combining 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 under various combustion conditions, carbon buildup can occur causing misfires. The thermal edge of the ceramic insulator discharges to help decrease carbon deposits.
  
  
• Spark Support Gap
  Discharge occurs in the spark support gap (space between the tip of insulator and the base of the outer electrode) to help prevent carbon buildup.
