HKS 50003-M35iL Iridium M-Series Super Fire Racing Spark Plug

The HKS 50003-M35iL is a high-performance M-Series Super Fire Racing iridium spark plug engineered to deliver improved ignition performance, enhanced durability, and superior resistance to carbon buildup under demanding conditions. Designed for enthusiasts running high-compression or turbocharged applications, this plug provides reliable ignition even under high load and extreme temperatures.

Key Features:

• 0.6mm Iridium Alloy Center Electrode: Ultra-fine electrode provides stronger, more focused spark for improved combustion efficiency and throttle response
• Platinum Chip Outer Electrode: Precious metal construction ensures extended service life and consistent performance
• Short Type Outer Electrode: Anti-vibration design reduces electrode stress and prevents premature wear in high-RPM applications
• Thermal Edge Technology: Optimized heat dissipation prevents pre-ignition and detonation
• Spark Support Gap: Enhanced gap design maximizes flame kernel development for complete fuel burn

The iridium alloy center electrode features an exceptional melting point of 2,454°C (4,449°F), allowing it to withstand extreme combustion temperatures and high compression ratios without deterioration. The nickel-coated housing provides additional protection against corrosion and premature wear. M-Series plugs are specifically recommended for modified engines running elevated boost levels, aggressive timing, or demanding track conditions where reliability and consistent ignition are critical.

Note: Spark plugs are sold individually. Verify the correct heat range and quantity required for your specific application.
