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. The Z4 M's six individual throttle bodies have been bored to a larger internal diameter facilitating air-flow to the combustion chamber for further increases in power, as well as more immediate throttle response.
