HKS 50003-M35 Iridium M-Series Super Fire Racing Spark Plug

The HKS 50003-M35 is a high-performance M-Series Super Fire Racing spark plug featuring advanced iridium alloy construction for superior ignition performance, durability, and resistance to carbon buildup. Engineered for enthusiasts running high-load applications and advanced tuning, this spark plug delivers reliable ignition under extreme conditions.

Key Features:

• 0.6mm iridium alloy center electrode for consistent spark and extended service life
• Outer electrode with platinum chip for enhanced durability
• Short-type outer electrode design provides superior anti-vibration properties
• Thermal Edge technology optimizes heat dissipation
• Spark Support Gap ensures reliable ignition under high compression
• High melting point of 2454°C withstands extreme combustion temperatures and minor knock events
• Nickel-coated housing prevents premature deterioration

The M-Series is specifically recommended for applications requiring reliable ignition, long-term durability, and anti-carbon buildup characteristics under high load conditions. The iridium alloy construction allows for a narrow electrode core without sacrificing longevity, delivering improved throttle response and efficient combustion. Available in colder heat ranges (7 and up) for high-performance applications, with heat ranges of 9 and up offered specifically for rotary engines.

Note: Spark plugs are sold individually.
