Two High-Performance DV+ Options for VAG Models

The GFB T9381 is the latest addition to the DV+ diverter valve lineup, engineered to deliver the performance benefits expected from GFB:

• Sharper throttle response
• Faster boost recovery after gearshift or throttle lift
• Improved boost holding
• Exceptional durability, backed by GFB's Lifetime Warranty

The well-known GFB T9351 DV+ remains a popular and proven solution. It replaces the problematic factory electronic valve mechanism while reusing the OEM solenoid—offering impressive performance at a cost-effective price point.

However, the T9351 adds 11mm to the height of the original diverter, which can create clearance issues in certain applications, such as:

• 2013.5+ Jetta GLI
• MQB-platform vehicles with aftermarket intakes or IS38 turbo upgrades
• Audi 4.0 TFSI engines from 2012–2017

This is where the GFB T9381 excels. With its low-profile integrated solenoid, it is even more compact than the OEM diverter, making it ideal for space-constrained engine bays.

The T9381 is also a great choice if you want to replace the entire factory diverter rather than reuse the existing solenoid—particularly in cases where the OEM solenoid is damaged or faulty.

Both the T9381 and T9351 ensure maximum boost retention, rapid throttle response, and long-lasting reliability.
