Description

The Whoosh Blow Off Valve Adapter for the Fiesta ST (2014-2019) provides the distinctive "whoosh" sound enthusiasts desire. This adapter installs between the stock bypass valve and turbocharger, redirecting excess boost pressure to the atmosphere. The installation process is straightforward, requiring only a 5mm hex key and the included hardware. The adapter is available in three vibrant anodized colors, though availability may vary. Note that the OEM valve is not included with this adapter. The adapter is specifically designed for the Fiesta ST models from 2014 through 2019. Installation is reported to be easy, with many users completing it in 30 minutes or less. Customer reviews highlight the loud, satisfying "whoosh" sound and the head-turning effect it has.
