HKS 50003-M45I Spark Plug 9 (ISO) for SUBARU EJ207 / EJ205 / TOYOTA 1JZ / 2JZ / PORSCHE 996T / 997.1 Turbo

Description High-Performance Spark Plug 9 (ISO) for SUBARU EJ207 / EJ205 / TOYOTA 1JZ / 2JZ / PORSCHE 996T / 997.1 Turbo

The HKS Super Fire Racing M45i spark plug is specifically developed for tuned and factory turbocharged engines operating under high thermal and mechanical loads. Designed to deliver improved ignition efficiency, exceptional durability, and anti-fouling performance, this plug utilizes a 0.6 mm iridium center electrode and a platinum chip on the ground electrode for maximum spark stability even under lean air-fuel ratios or high boost pressure.

• 0.6 mm iridium alloy center electrode reduces voltage requirements and enhances ignition under load
• Platinum-tipped ground electrode improves combustion reliability and wear resistance
• Compact, conical-shaped ground electrode reduces mass and resists vibration for longer service life
• Thermal edge on the insulator minimizes carbon buildup during extended idling
• Spark support gap ensures consistent discharge and fouling resistance
• Ideal for high-performance applications where stable ignition is critical
