A velocity stack that smooths air into an individual throttle body for cleaner flow and sharper throttle response.
A velocity stack — or intake trumpet — fits over the mouth of an individual throttle body (ITB) or carburettor. Its flared bell shapes the incoming air so it enters the bore with less turbulence, which helps airflow and throttle response on ITB and carburetted setups.
Tell us your ITB size/type and we'll confirm the correct trumpet (and quantity).
