GFB DV+ Low Profile Valve - EA839 3.0T / 2.9TT
2.9 V6 Twin Turbo Models require 2x Valves to be purchased. 

The T9380 is the latest addition to the DV+ range of diverter valves from GFB (Go Fast Bits). It is specifically designed as a complete replacement for the newer generation of Continental brand OEM diverter valves found in late-model VW and Audi vehicles.
Unlike the earlier generation diverter valves manufactured by Pierburg, the newer Continental valves cannot be disassembled and integrated into a DV+. Therefore, GFB developed the T9380 with a low-profile integrated solenoid as a complete replacement for the Continental diverter valve, enabling a hassle-free installation with no clearance issues.

Like all valves in the DV+ range, the new T9380 delivers the following benefits over the OEM diverter valve:

  • Improved boost holding
  • Sharper throttle response
  • Faster boost recovery after a gearshift or brief throttle lift
  • Unrivalled longevity, backed by our Lifetime Warranty
  • Improved Boost Holding

When GFB engineers performed boost leak testing on the OEM diverter valve in a VW Mk8 Golf R, they found the leak was significantly larger than in earlier generations.
This excessive leaking is due to the emerging trend of manufacturers mounting diverter valves remotely on plastic piping rather than directly on the turbocharger. A plastic valve mechanism closing onto a plastic seat resulted in the largest OEM diverter valve leak we’ve seen yet at 28L/min at 1 Bar of boost.

Even with the Viton face seal (featured on all DV+ pistons), the plastic OEM seat face was found to be so uneven that it was impossible to achieve a reliable seal. The T9380 successfully addresses this issue by incorporating an integral piston seat machined into its body. This design ensures a proper seal, even on uneven plastic OEM seats.

Awesome GTI Delivery Information


For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.

Do we ship abroad ?

Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !

However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.

Why is postage on bulky items to some countries expensive compared to some other companies ?

For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
