It offers a performance boost by releasing excess boost pressure when the throttle closes. This vent-to-atmosphere BOV creates a distinctive sound, appealing to enthusiasts seeking enhanced acoustics. Made from durable materials like anodized aluminum, it resists heat and corrosion, while its adjustable spring tension allows for tuning based on specific setups. The VTA BOV improves throttle response and reduces turbo lag by preventing compressor surge.

The VTA is a performance blow-off valve solution for Audi or VW vehicles with an electronic factory diverter valve.

Choose Your Sound…

With the removable extended trumpet, you can configure the T9401 to give you either a classic “whoosh”, or the loudest, most unique whistle sound you’ve ever heard on a Euro vehicle!

Customize the sound!

The T9401 also features adjustable spring pre-load so you can fine tune when it blows off, and for how long. A softer pre-load allows the valve to blow off for longer and at lower engine loads. If you prefer to hear it only at higher engine loads you can use a firmer pre-load.

Low-Profile, Easy Installation

Using our integrated solenoid design stacked in an “over/under” configuration, the super-low profile allows clean and simple fitment (even if your aftermarket intake is using up all the space!)
