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 kit includes our machined aluminum adapter, 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.
