DESCRIPTION
 

Steeda ProFlow Blow-Off Valve Adapters (also called Bypass Valve Adapter) give your engine the sound to match its performance. These adapters will convert your factory re-circulation valve into a blow-off valve, giving it the iconic turbo sound!

CNC-machined in-house from aerospace-grade 6061 billet aluminum, ProFlow BOV adapters are easy bolt-on parts that require no modification or tuning.

On high-boost applications, they also help to prevent turbo surge, by allowing the pressure to vent to the atmosphere. The adapters are available for fitment on a variety of Ford Mustang, Maverick and Fusion vehicles from 2015 and up.

FEATURES
 
  • Releases excess boost pressure into the atmosphere
  • Converts the factory recirculation valve into a blow-off valve
