Want more power? Upgrade your motorcycle equipped with the stock airbox by installing the Norman Hyde Bellmouth. This product is designed to eliminate the intake snorkle located on your stock airbox creating a larger intake for more horsepower, torque, and throttle response. This product combined with British Customs Exhaust, NGK Iridium Plugs, K&N Filter, and Proper Tuning is the best performance upgrade without removing your air box.
