Special Note: Dinan throttle body production is temporarily suspended as we repair necessary equipment needed for their production. Any order placed for throttle bodies will immediately be put into back order. Website will be updated once throttle body work goes back to active production. Dinan's High Flow Throttle Body improves intake air flow for additional horsepower and torque gains. The internal diameter of the stock throttle body has been increased for additional air flow area.. The resulting increase in air flow provides more horsepower and torque throughout the rpm range with noticeably quicker throttle response.
