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, and a short-reach design tailored for moderate-to-high performance two-stroke applications requiring a 1/2" reach.

TSO Garage Note: A medium-cold heat range (8) short-reach (12.7mm) standard resistor plug. The BR8HS acts as the short-reach counterpart to the legendary BR8ES. It is an incredibly versatile workhorse heavily utilized across high-output 50cc two-stroke scooters, youth dirt bikes like the early KTM 50s, a massive array of vintage 1970s–1980s air-cooled enduros, and various two-stroke marine applications operating under heavier thermal loads.
