Bosch 74mm (RS3) E-Throttle Conical Adapter


Our bolt-on adapter allows fitment of the 74mm Bosch Motorsport or Audi RS3 electronic throttle body to the Audi S2/S4/S6 intake manifold flange.

This conical adapter is best suited to forward facing intakes and provides a smooth transition from throttle plate to intake.

For use with a forward facing S2 intake manifold, the geometry is optimised to allow the use of the Audi RS3 alloy intake elbow which includes provision for an E-bypass valve and 4 pin Bosch TMAP sensor for improved Intake Air Temperature measurement.

Machined from billet 6082-T6 aluminium and anodised. Supplied with Viton o-rings (no need for gaskets!).
