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 re-purposing 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.
VTA or DV+?
Depends if you want sound or not. Both valves are constructed with the same quality materials and valve mechanism, and both offer the same performance and reliability benefits. However, the VTA vents to atmosphere for sound whilst the DV+ recirculates the air to keep it quiet.
Why choose a VTA over a “BOV spacer”?
“BOV spacers” are cheap and they make sound. But that’s it. All the inherent performance and reliability issues you get with the factory diverter valve remain, because a spacer doesn’t change the diverter valve in any way. The VTA improves the operation of the diverter valve for sound AND performance.
Why choose a VTA over a kit that includes a solenoid?
Because there’s no performance benefit to replacing the factory solenoid, only a much higher price! If a VTA with the factory solenoid can open in a couple of hundredths of a second, why pay more than you need to?
- TMS Technology for faster boost recovery on gearshift and during throttle modulation
- Improved boost holding ability
- Atmosphere venting for blow-off sound
- Retains ECU control
- Simple, direct bolt-on kits include everything you need to install
- Manufactured in Australia in accordance with ISO 9001

VTA blow off valve.
This product improved the performance of my car dramatically. And the sound is awesome. I recommend this if you are into speed and performance. Also very easy to install.
The fit and finish is perfect. The sound really turns heads
Overall great product, was a bit of a pain to get under the car with out a lift but it went ok with a floor jack. Easy to install about 40 min max, it has worked great so far.
I have a 2009 Mk5.5 GTI and am very pleased with difference this product made. The only modifications on my car is an aftermarket cold air intake system, and the VTA BOV. You can notice a small difference in throttle response but the real catch is the sound. The car went from making almost no sound to vvvvvshhhh every time you took your foot off the gas. It sounds even better from the outside of the car hearing it rip down the road. The sound in my opinion is not obnoxious. If you like your music loud it won't interfere and if you roll your windows up it pretty much vanishes. Overall I am very pleased with the product and would recommend it to anyone looking for the signature turbo BOV sound.
Shipping was extremely fast and installation was a breeze. Took me about 20 minutes to install everything and the results were worth. I've been breaking necks ever since the install.
Braaannggg!!! Braaannggg!! Pshhhh!!! What you will hear when you install the product.
