Fits 22+ WRX
For adjustability this piece has nine threaded holes, we ship this piece with 3 of the holes open and we also include a 2mm allen key for removal. For fine tuning, remove and add screws as desired to reach the amount of venting or recirculation you are looking for.
The adapter will always partially recirculate even with all the vent holes left open.
This high performance adapter mounts between the OEM bypass valve/solenoid and the mounting location causing the unused charge air to vent to atmosphere (VTA) giving off the well known, but distinct sound all turbo owners know and love! The adapter bolts right in with the included longer bolts, no other modifications or tuning are required. Precision CNC machined out of high quality aircraft grade billet aluminum and available in 4 different colors
Installation is simple and all mounting hardware is included.
