Premium Iridium Spark Plug for High-Performance Engines

Engineered with ultra-fine iridium tip for enhanced durability and consistent spark performance, ensuring optimal combustion efficiency. Precision laser-welded construction minimizes voltage requirements while maximizing ignition reliability.

Direct replacement for NGK LZFR5C11, Bosch FGR8MQPE, Champion REC12MCC4, and Denso K16HPR-U11, compatible with a wide range of automotive and small engine applications. Ideal for high-compression engines, turbocharged systems, and performance tuning.

Triple gasket sealing design prevents gas leakage under extreme pressure, while anti-corrosion nickel-plated shell extends lifespan. Optimized heat range reduces pre-ignition risk in demanding conditions.

Global wholesale pricing ensures unbeatable value for bulk orders, backed by rigorous OEM-equivalent quality testing. Stock up for fleet maintenance, auto repair shops, or industrial equipment servicing.

Exclusive high-conductivity core material delivers 20% faster cold starts compared to standard copper plugs. Trusted by professional mechanics for its precision gap tolerance (±0.1mm) and vibration-resistant internal structure.
