CHAMPION Spark Plug - RN3C 880

Reliable spark plug performance directly impacts engine efficiency and throttle response—especially critical under high-RPM racing conditions where marginal ignition delays compound into lost horsepower. The CHAMPION RN3C 880 delivers consistent spark energy with thermal stability across demanding operating ranges, ensuring your engine fires cleanly lap after lap. If you're running tight tolerances or pushing boost, a quality spark plug isn't negotiable.

Built with a copper core center electrode for precise heat range management, the 880 resists fouling while maintaining stable combustion temperatures. The integrated SAC-9 semi-conductor resistor suppresses EMI and RFI noise that can interfere with modern ignition systems and engine control modules. An Ultraseal™ coated shell protects against corrosion, extending plug life even in harsh underhood environments.
