HKS 50003-M45iL SPARK PLUG SUPER FIRE RACING NGK 9 NISSAN TB48

The HKS Super Fire Racing M45IL spark plug is a premium iridium-based ignition solution engineered for high-load and high-compression turbocharged engines. Designed to optimize spark efficiency, resist carbon fouling, and deliver extended durability, this plug features a 0.6 mm iridium center electrode, platinum-tipped ground electrode, and anti-vibration construction to maintain consistent performance under extreme operating conditions.

• 0.6 mm iridium alloy center electrode ensures high ignition performance and longevity
• Platinum chip on ground electrode enhances spark efficiency and thermal resistance
• Short-type anti-vibration ground electrode improves durability and spark stability
• Thermal edge reduces carbon deposits during extended idling or variable combustion states
• Spark support gap design prevents fouling and improves spark discharge reliability
• Nickel-coated shell resists corrosion and wear
