Reverse Inlet Manifold Wedge
Subaru Impreza Version 3 - 4

The Reverse Inlet Manifold Wedge allows you to reorientate the angle of the throttle body when rotating your Version 3 or Version 4 (Phase 1.5) inlet manifold.

The wedge is cut with an elliptical hole in the centre, this allows it to align perfectly with the inlet manifold once welded on, i.e. there are no lumps or bumps to be smoothed out with a flapwheel. It is also supplied with four M8-tapped holes ready for you to bolt your throttle body straight on as well as being nicely chamferred to ensure a tidy installation against the OEM flange.

If desired i can arrange to have a wedge welded on to a manifold supplied by either yourself or from stock. If this interests you please contact me to discuss your requirements further.
