Ultimate spark plug "M"
Ignitionability, durability, anti-insulation are all reinforced. HKS has made the best plug for both tuning engines and stock engines.
Performance and Efficiency
Increased Ignition Performance Decreased voltage requirement strengthens ignition performance under harsh conditions like lean mixture or high boost pressure.
Improved Durability New material and design improve durability which allows for use under hard combustion conditions like continuous high load during circuit driving or aggressive tuning. * Improper combustion condition and wrong heat range selection may cause damage to the spark plug.
Decreased Carbon Deposits Thermal edge and spark support gap help prevent carbon buildup for better ignition under various combustion conditions
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.
