This adapter flange is designed to allow the Q45 throttle body to bolt directly onto an intake manifold that would normally have a Honda K series drive by wire throttle body. The Q45 throttle opening is 80mm and the adapter necks down to 70mm for the Honda side of the flange.

The flange is made from 6061 T6 aluminum and comes with the required bolting hardware for the plenum attachment, you will need to supply the 8mm bolts for the throttle body itself.

Note that the Q45 bolt pattern has been rotated clockwise to accommodate both bolt patterns.
