This adapter allows one to bolt a Bosch 82mm drive by wire throttle body or 74mm Bosch DBW TB to the OEM FD3S or the Turblown Rotary Upper Intake Manifold. Double o-ringed front and back for leak free assembly when using with the Turblown UIM. O rings included. Does require an ecu capable of DBW control such as a Haltech elite 1500/2500 or Nexus, etc. If you are using this with the OEM FD3S upper intake manifold you will want to do some port work to radius the plenuem divider( not required on the Turblown UIM).
The optional bosch DBW pedal, does require a mount to be fabricated( we are working on these, but a long ways out).
