Honda B/H-Series Throttle Body to Nissan Q45 Plenum Adapter

Description

Already have a large throttle body for that Honda motor or just don’t want to go 80mm Q45? We make these adapter flanges to go from the Q45 pattern we use on our plenums to the Honda B series type pattern with a 74mm bore. CNC cut from 1/2″ billet 6061, we’ve relieved one side for the throttle cable quadrant and the symmetrical pattern of the Q45 allows you to rotate the adapter to index the Honda throttle body. We also include the bolts required for the adaptation.

This adapter is to put B or H series throttle body onto a Q45 plenum.
