The HKS Super Fire Racing M50HL is an HL-type iridium spark plug with an NGK 10 equivalent heat range — the high heat-range option for heavily tuned engines. With its M12 long-reach, 14 mm hex design, it fits the Nissan GT-R R35 (high-tune setups) and Toyota 86 / Subaru BRZ (FA20), where the colder heat range controls detonation under high load and boost. The 0.6 mm iridium center electrode and reinforced outer electrode provide steady ignition at high RPM. Sold individually.
