T9381 GFB Diverter Valve DV+
We are excited to introduce two DV+ options for VAG models: the T9381 and the T9351. Both models offer outstanding performance and durability, catering to different needs and applications.
Features
- Sharper Throttle Response
- Faster Boost Recovery: After gearshift or brief throttle lift.
-
Improved Boost Holding
Unrivaled Longevity: Backed by our Lifetime Warranty.
The T9351 has been the reliable workhorse of the DV+ family. It provides excellent performance at a lower cost by replacing the problematic valve mechanism of the factory electronic diverter while reusing the solenoid.
Height Considerations
The T9351 increases the overall height by 11mm, which may cause clearance issues in certain models:
- 2013.5+ Jetta GLI
- Any MQB platform with an aftermarket intake or IS38 turbo
- Audi 4.0 TFSI from 2012-2017
The T9381 features a low-profile integrated solenoid, making it shorter and more compact than even the factory diverter. This ensures a fit for the tightest applications.
Versatile Use
The T9381 can replace the T9351 when you prefer to replace the entire factory diverter valve rather than re-use the factory solenoid, especially if the solenoid is faulty.

Color stain
Color: Burgundy, Size: X-Large
Very good design and well fitted for an XL; however, the clothing stained my wife beater with the reddish color making it hard to wash out.

Sharp shirt, smooth style, smiles shine!
Color: Maroon, Size: XX-Large
I got the COOFANDY Men’s Stretch Dress Shirt (Long Sleeve, Regular Fit) for my best friend’s wedding, and it was fantastic. I matched it with my fiancé’s outfit, and the vibrant color looked amazing in photos. The fabric is smooth, the fit is flattering, and the shirt is stretchy in all the right places, making it incredibly comfortable to wear all day.
I felt sharp, confident, and stylish — exactly what you want for a formal event. The buttons, stitching, and overall quality are solid for the price.

Nice quality shirt, true to size
Color: Light Green, Size: XX-Large
Nice material and fit is accurate. However shirts are rolled up in a tube, so if you need to wear the shirt the day you receive it be prepared to iron it!
