An all-new product for the 2.5T FSI engine as found in the Audi TT-RS and RS3, this replacement cast elbow increases the discharge port opening to a sufficient size to vent more pressure when the engine is tuned to produce more boost or is equipped with a modified or larger than stock turbo.

The OEM elbow does not flow sufficient air at throttle lift on modified applications which can result in a fault code in the ECU, and potentially a reversion of pressure into the compressor that could lead to compressor surge, and slower boost response upon reapplication of the throttle.

This kit includes an all-new valve that can be setup either as a recirculating valve for quiet operation, or as an atmospheric blow-off valve for increased discharge sound.
