Specific Product Information

Description

The best-sounding BOV for your Mk5 or Mk6 GTI!

New fitments unlocked! The T9409 picks up new VAG fitments not covered by the existing T9401.

On vehicles using transverse-mounted EA113, EA888.1 or EA888.2 engines such as the Mk5 and Mk6 GTI, clearance issues prevent the T9401 from being a bolt-on fit.

The T9409 however moves the trumpet to a different position, allowing it to fit on these popular models.

 

Choose Your Sound…

With the removable extended trumpet, you can configure the T9409 to give you either a classic “whoosh”, or the loudest, most unique whistle sound you’ve ever heard!

… Then Tune It!

The T9409 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.

Direct Bolt-On Fit, No Modifications Needed, No Compromise

Remove the OEM diverter, bolt the T9409 in its place. No cutting, no modification, no issues – just sound and performance!

Is This the Right Valve for Me?

If you haven’t already checked that your vehicle is on the fitment list, do that first. (SELECT BY CAR LINK). If you can’t find your vehicle in that list, contact us!

If you get a few different valve options for your vehicle, use the guide below to make sure you’re choosing the right one for your needs:

T9409 VTA – Offers the loudest, most obnoxious and unique sound possible, as well as the classic “whoosh” (trumpet removed). Best choice if you love turbo noises and want something unique.

T9481 and T9451 VTA – Both offer the classic “whoosh” sound. T9481 includes the solenoid, T9451 re-uses the solenoid from the factory diverter. Best choice if you want to stick to the classic sound.

T9381 and T9351 DV+  The DV+ doesn’t vent to atmosphere, so it doesn’t make sound. You can hear a subtle air release if you have an aftermarket intake fitted, but otherwise it is silent. T9381 includes the solenoid and T9351 re-uses the solenoid from the factory diverter. Best choice if you don’t want attention!

Sharper throttle response, reliable boost holding

As with all GFB DV+ and VTA products, improved throttle response and boost holding are baked-in standard features.

The OEM moulded plastic diverter valve cannot match the performance of GFB’s precision CNC machined metal construction and Viton seals.

Unrivalled longevity, backed by our Lifetime Warranty

The combination of precision manufacturing, attention to detail, and robust materials mean the VTA will last a lifetime. So does the warranty!

Uncompromised throttle response

Modern OEM electronic diverter valves might be faster than pneumatic types, but they are binary in operation – open or shut. What they gain in operational speed, they lose in throttle response. The VTA adapts the method of operation of the factory diverter system to give you the best of both worlds.

Pilot Operation – the patented design of the VTA means the piston is not directly connected to the solenoid, so it can open and shut progressively. This operation method leads to improved throttle response and drivability, because the VTA is more “discerning” about how much air it vents when triggered by the ECU – it only vents the amount of air necessary to eliminate pressure spikes that cause compressor surge, where the factory diverter opens fully whether it needs to or not.

When you close the throttle during spirited driving, the VTA opens to prevent compressor surge and protect the turbo. When the pressure has dropped sufficiently, the piston begins closing to preserve a small amount of boost in the intercooler for as long as possible. This helps the turbo return to peak boost faster when you re-open the throttle. We call this the Turbo Management System (TMS) benefit.

Lightning-fast operation – vehicle manufacturers use an electronic diverter valve because they respond faster than pneumatic valves. Well, the VTA is faster again! No other valve on the market comes close to matching the VTA opening and closing speeds.

Hold my boost and watch this…

Your turbo works hard to create boost, so why make it work harder than it needs to? A GFB VTA ensures that all your hard-earned boost makes it to the engine.

Unsurprisingly, the moulded plastic valve components in the factory electronic diverter valve don’t seal that well. A boost leak from the factory diverter valve will cause the ECU to drive the turbo harder to compensate for the loss, resulting in higher turbo RPM, more exhaust backpressure, and hotter compressor outlet temperatures. So even though your tune might still hit target boost, a diverter leak means the turbo is more stressed, and the engine makes less power.

The VTA replaces the factory diverter’s loose-fitting plastic valve with precision CNC machined metal components and a durable elastomer piston seal. Because the VTA design uses boost pressure to force the piston shut, it doesn’t matter how much boost you throw at it – a VTA won’t fail, leak, or blow open.
