High-performance racing spark plug featuring a specialized nickel alloy electrode configuration built to withstand grueling racing conditions. Built with a solid 98% pure copper core for enhanced heat dissipation, trivalent metal plating for superior anti-corrosion and anti-seizing properties, a built-in resistor, a non-projected tip design, a factory pre-gapped 0.8mm / 0.031" gap, a strengthened ground electrode, and a solid terminal configuration explicitly designed to resist vibration loosening.

TSO Garage Note: A cold heat range (9) racing plug variant featuring a solid terminal post and a reinforced ground strap configuration (denoted by the "-N-8" specification). While sharing the core thermal and heat range characteristics of a standard BR9-series plug, this specific configuration is tailored for late-model high-performance applications like the final generation Honda CR250R, where the solid terminal and strengthened physical structure help combat high-frequency vibration and severe racing loads.
