Standard OE-approved copper core spark plug featuring a solid 98% pure copper core for enhanced heat dissipation and wider heat ranges. Built with trivalent metal plating for superior anti-corrosion and anti-seizing properties, a built-in resistor, a short-reach design tailored for moderate-to-high performance two-stroke applications, and a solid terminal configuration explicitly designed to resist vibration loosening.

TSO Garage Note: A medium-cold heat range (8) short-reach (12.7mm) standard resistor plug with a solid terminal nut. This is the exact solid-terminal equivalent to stock #4322 (the standard BR8HS). While it functions identically internally, the solid terminal makes it an essential choice for high-vibration applications like older two-stroke personal watercraft (PWCs), youth dirt bikes (such as early KTM 50s), and snowmobiles like the Yamaha Bravo where standard removable nuts are prone to vibrating loose and causing ignition issues.
