HKS Super Fire Racing Iridium Spark Plugs - M50HL - Toyota GR86 / 86, Subaru BRZ, Scion FR-S (FA24, FA20)

The M50HL is a plug and play spark plug for Toyota GR86, Toyota 86, Subaru BRZ or Scion FR-S. Works for FA24 or FA20 engines.

The 50 heat range that HKS uses translates to a 10 heat range on the NGK spark plug scale or a 31 on Denso spark plug scale.

The Super Fire Racing M-series Iridium Spark Plugs are designed for improved ignition performance, durability, and reliability over stock plugs. The plugs feature a 0.6mm Iridium Alloy Center Electrode that reduces the voltage requirements and improves the durability and performance of the ignition. The outer electrode incorporates a square platinum chip that when combined with the iridium center, also boosts the ignition performance. The thermal edge and spark support gap help prevent carbon buildup on the plug to make the plugs last longer under various combustion conditions. To prevent premature detonation, the use of a nickel coating on the housing is applied to add that extra safety measurement.
