By popular request, we've designed a throttle body adapter that makes it easy for customers running our KPower manifold to install a drive-by-wire (DBW) throttle body with the correct bore size. This adapter works with the popular and affordable 74mm Bosch throttle body, part #280750474.

Our version 2 design offers some additional wall thickness along two sides to create a better seal. To do this, two bolt holes have been undercut so the socket heads now sit below the throttle body mating surface. 

This updated carbon 3D-printed design isolates engine vibration that can cause throttle bodies to fail and bolts to come loose and break., this kit includes all mounting hardware, and both gaskets for a simple and clean installation. A 1/8" reinforced rubber gasket is now included, along with plastic isolating washers to keep throttle body vibration to a minimum. Customers with DBW setups should also consider adding our IACV block off plate.
