Volkswagen Blow Off Valve Adapter by Boomba

This high performance adapter mounts between the OEM bypass valve/solenoid and the turbo housing, 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.

Installation is simple (car does not need to be raised) and all mounting hardware is included.


  • Precision CNC From Aircraft Grade Aluminum
  • Mounts Between BPV/Solenoid and the Turbo Housing
  • Vents Unused Charge Air to Atmosphere
  • Direct Bolt-On With Hardware Included

Please Note: No aftermarket tuning required. Will work on stock tune or aftermarket tunes.

One of the greatest simple products you can buy

Honestly one of the best easy bolt on mods that I’ve ever purchased. It makes my GTI that more special and it gives it such a road presence for sure

I lost throttle response and expected a bit louder than it shows on videos

Great BOV

Better than the ECS BOV

Blow off adapter for 2017 Passat 1.8t

Purchased a BOV adapter for my car. Website said it would fit. Took it to a shop that specializes in VW and they wouldn’t even do it. They said once the adapter is on the diverter would be up against the head. I spent money and my time for nothing. This website needs to be more accurate and less worried about making a dollar.
