GFB VTA Blow Off Valve for 2005-2020 Audi, VW, and Porsche (2.0T) T9481

Fits select 2005-2020 Audi, Volkswagen, and Porsche models (2.0T) equipped with the Pierburg-branded factory diverter valve.

The GFB VTA (Venting to Atmosphere) combines the signature blow-off sound enthusiasts crave with the performance-proven technology of the Go Fast Bits DV+ series. Designed as a direct bolt-on replacement for the often-unreliable factory solenoid, the VTA ensures superior boost holding and sharper throttle response by utilizing a pilot-actuated valve mechanism. Unlike the factory plastic valve that can leak or fail under high boost, the VTA is engineered to remain sealed until the optimal moment, providing faster boost recovery during gear shifts.

The T9481 features a low-profile integrated solenoid that eliminates the need for remote mounting or complex hose routing, making installation a straightforward process in tight engine bays. Each unit is manufactured in Australia to exacting tolerances and is backed by a limited lifetime warranty.
