HKS Super Fire Racing M40iL Spark Plug 1993-2002 Toyota Supra JZA80 2JZ-GTE

The HKS Super Fire Racing M40iL is an iridium spark plug built for racing engines requiring M14 thread, 40.4mm reach. It delivers consistent spark in high-boost turbo applications on vehicles like Toyota Supra 2JZ-GTE, Nissan Skyline RB26DETT, and Subaru Impreza WRX STI for better combustion efficiency and power delivery. Ideal for track days and tuned street cars seeking reliable performance.
