GFB T9381 DV+ Low Profile Diverter Valve VAG 2.0T TFSI / TSI

The GFB T9381 is the latest addition to the DV+ family and offers all the well-known benefits expected from a DV+ upgrade:

• sharper throttle response
• faster boost recovery after gear changes or brief throttle lift-off
• better boost holding
• exceptional durability, backed by a Lifetime Warranty

What makes it stand out?

The T9351 model is the proven "workhorse" in the DV+ range. It replaces the problematic valve mechanism of the factory electronic diverter valve, while retaining the original solenoid, which keeps the price reasonable and the benefits high.

However, with the T9351, there is an increase in overall height by 11 mm, which in some applications can create space issues.

This is especially true for:

• all 2.0T gasoline engines from 2003 to 2020
• Audi 4.0 TFSI (2012–2017)
  (2 units required)

This is where the T9381 comes in

The T9381 uses a low-profile integrated solenoid, making it lower and more compact even than the factory diverter valve. This ensures installation even in the tightest applications where the standard DV+ might not have enough space.

In addition, the T9381 can also be used as an alternative to the T9351 when you prefer to replace the entire factory diverter valve, instead of reusing the original solenoid – for example, if the factory solenoid is defective.

Key advantages:

• Sharper throttle response
• Faster boost recovery
• Better pressure holding
• Compact low-profile design
• Suitable for tight engine bays
• Replaces the entire factory diverter valve
• Also suitable if the OEM solenoid is defective
• Lifetime Warranty

An ideal choice for enthusiasts looking for a more compact DV+ solution with maximum reliability, OEM+ fitment, and a real improvement in response and boost, especially in space-constrained applications.
