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】
- R35 GT-R stock's heat range is the same as NGK 8, NGK 9 to 86/BRZ, and the new HKS M50HL is the same as NGK 10. It's for a high tuning vehicles.
- Reinforced by making the outer electrode bigger(see the pictures below). 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.
Ensured wide area of combustion by optimizing the position of the outer electrode and central electrode. It has a more efficient flame spread than the normal iridium spark plug.
