GFB T9451 DV+ Diverter Valve for VW Audi 2.0T FSI TSI Direct Replacement

The GFB T9451 DV+ is a high-performance diverter valve designed as a direct replacement for 2.0T FSI and TSI engines found in Volkswagen and Audi (VAG) applications. This atmospheric diverter valve combines the reliability of a piston-type valve with GFB's innovative pressure-balanced technology to deliver superior boost control and throttle response.

Key Features:

• Direct bolt-on replacement for factory diverter valve - no modifications required
• Pressure-balanced piston design prevents boost leaks and maintains optimal boost pressure
• Atmospheric venting configuration produces distinctive blow-off sound on throttle lift
• Rapid boost recovery during gear changes for improved acceleration and performance
• CNC-machined aluminum construction with anodized finish for durability
• Upgraded internal components resist heat and wear better than OEM valve
• Includes all necessary hardware and O-rings for complete installation

The DV+ addresses common failure points of the stock diverter valve, including torn diaphragms and weak springs that lead to boost leaks and performance loss. The piston-type design eliminates the fragile diaphragm found in OEM valves, while the pressure-balanced system ensures the valve opens and closes precisely when needed. This results in sharper throttle response, maintained boost pressure under load, and the satisfying sound of atmospheric venting between shifts.

Compatible with 2.0T FSI and TSI turbocharged engines across the Volkswagen Audi Group (VAG) lineup, including models such as VW GTI, Golf R, Jetta, Passat, Audi A3, A4, TT, and S3. Installation typically takes 30-45 minutes with basic hand tools.
