GFB T9451 VTA For VAG 2.0FSI and TSI Turbo Engines


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

If you want sound with your performance (or performance with your sound!), GFB’s VTA delivers just that! By combining the proven performance benefits of our ground-breaking DV+ with atmosphere venting, the VTA delivers an aggressive blow-off sound, improved throttle response and boost recovery, as well as superior boost holding and reliability in extreme conditions. The VTA shares the successful DV+ design philosophy: “Keep what works, replace what doesn’t”
This means we retain ECU control and the solenoid from the factory diverter to ensure the fastest possible response time, without the added and unnecessary cost of replacing the solenoid like some brands do.
The weak part of the factory diverter has always been the plastic valve mechanism – this is the part we replace. The VTA features CNC machined billet components that last a lifetime, and we also change the valve operation method for better performance.
The factory diverter valve can only operate in two states – open, or closed. When it opens fully at low boost, or during a partial throttle lift mid-corner, it causes increased lag and a noticeably non-linear boost transition.

GFB pioneered the use of “pilot operation” in the DV+, which works by repurposing the factory solenoid to control the pressure behind the piston rather than the piston itself. This allows the solenoid stroke to be much shorter, speeding up the response time and increasing the actuation force.
More importantly, it allows the piston to open and close progressively in response to the amount of boost pressure present, which smooths boost transitions and reduces the lag caused by the factory diverter valve.
It is this design philosophy that makes the VTA not only the best performing blow off valve solution, but also the best value on the market.

    As close to proper dump valve as you can get with these engines. Makes the noise when it should. Nothing like the atmospheric spacer things. 100% recommended if you like dump/ blow off valve sounds

  • Spot on!

    Upgraded from a Forge “blow off spacer”
    Suspected I was loosing boost. After fitting this I can assure you I was. Great quality product and the way it holds boost is phenomenal. This product fixed a problem I didn’t realise I had. Nice noise not OTT and all in all a great product!

    Brilliant Product. Didn’t expect anything less from GFB. Over the moon with the performance and sound. Easy to install well worth the buy.
