Triumph America & Speedmaster Air Intake Bellmouth
Triumph America & Speedmaster Norman Hyde Bellmouth
If you do not want to upgrade your intake system with the Triumph America & Speedmaster Air Box Removal Kit, the Norman Hyde Bellmouth is the next best thing. The Norman Hyde Bellmouth removes the stock snorkel and increases air flow through the stock air box. Jetting will be required and for best performance gains, we recommend installing a K&N air filter, NGK Iridium Spark Plugs, and British Customs Air Injection Removal Kit.
