TSO Garage Note: A medium-cold heat range (8) fine-wire iridium upgrade with a standard 19mm reach. It serves as the premium high-performance counterpart to standard plugs like the BR8ES or nickel racing plugs like the BR8EG. It is heavily favored as the ultimate anti-fouling, long-lasting upgrade for full-size two-stroke motocross and woods bikes, large-displacement ATVs, and modified high-output engines demanding maximum spark efficiency.
