XS-POWER Audi B5 S4 A6 Allroad 2.7T Billet Aluminum 007 Turbo Diverter Valves – BLACK PAIR
XS-POWER 007-STYLE PERFORMANCE DIVERTER VALVES • BLACK ALUMINUM • PAIR OF 2 • AUDI 2.7T TWIN TURBO
Upgrade the factory turbo bypass valves on your Audi 2.7T with this PAIR of XS-POWER black aluminum performance diverter valves. Designed for compatible Audi B5 S4 2.7T, C5 A6 2.7T and C5 Allroad 2.7T Twin Turbo applications, these piston-style recirculating bypass valves provide a durable performance-oriented alternative to the factory-style diverter valves.
IMPORTANT: THIS LISTING INCLUDES TWO (2) DIVERTER VALVES.
That's exactly what you want for the Audi 2.7L V6 BiTurbo / Twin Turbo platform, which uses a dual-diverter-valve configuration.
BUILT FOR THE LEGENDARY AUDI 2.7T
The Audi 2.7T remains one of the most popular European turbo performance engines ever produced. Whether you're maintaining a stock K03-powered B5 S4 or building a modified K04 turbo setup, proper boost-control and bypass-valve operation are important parts of the turbo system.
When the throttle closes under boost, the diverter valves provide a controlled path for pressurized charge air to recirculate rather than forcing that pressure back against the compressor wheels.
These XS-POWER valves are designed to provide a responsive, reusable piston-style bypass valve solution for compatible Audi/VW turbo applications.
PAIR OF TWO – PERFECT FOR AUDI 2.7T TWIN TURBO APPLICATIONS
Don't accidentally order a single valve for your 2.7T.
YOU GET TWO BLACK XS-POWER DIVERTER VALVES IN THIS LISTING.
- Quantity: 2 Diverter Valves
- Black aluminum construction
- Piston-style bypass / recirculation design
- Designed for compatible Audi 2.7T applications
- Ideal for B5 S4 Twin Turbo applications
- Compatible C5 A6 2.7T applications
- Compatible C5 Allroad 2.7T applications
- Suitable for many additional compatible turbo applications
⚡ 007-STYLE PISTON DIVERTER VALVE DESIGN
These XS-POWER valves use a performance-oriented piston-style diverter / bypass valve design. Unlike a vent-to-atmosphere blow-off valve, a diverter valve recirculates discharged boost pressure back into the intake tract.
This type of recirculating configuration is especially appropriate for many MAF-equipped Audi and Volkswagen turbo applications where the engine management system has already measured the incoming airflow.
The result is a clean performance solution for enthusiasts looking to replace or upgrade their turbo bypass valves without converting the system to an atmospheric blow-off configuration.
BLACK ALUMINUM PERFORMANCE CONSTRUCTION
Forget the ordinary plastic appearance of many factory-style bypass valves. These XS-POWER performance diverter valves feature black aluminum bodies for a clean, purposeful appearance in the engine bay.
The reusable piston-style construction is designed for performance applications and gives enthusiasts the ability to select an appropriate spring configuration for the vehicle's setup.
- Aluminum valve body
- BLACK finish
- Performance piston design
- Recirculating / bypass configuration
- Replaceable internal spring
- Serviceable performance design
- Designed for turbocharged applications
SPRING OPTIONS / TUNING RANGE
Spring selection allows the valve response to be matched to the individual turbo application. Available spring ranges include:
| Yellow Spring | 15–23 PSI Guideline Range |
| Blue Spring | 23–30 PSI Guideline Range |
| Red Spring | 30+ PSI Guideline Range |
⚠️ IMPORTANT SPRING NOTE: The PSI figures above are spring-force guidelines and should NOT be interpreted as a direct one-to-one match with the vehicle's boost pressure. Correct spring selection depends on the complete turbo system, vacuum/pressure acting on the valve, engine calibration and individual vehicle setup.
AUDI 2.7T FITMENT
Designed for compatible Audi 2.7T Twin Turbo applications including:
- Audi B5 S4 2.7T Twin Turbo / BiTurbo
- Audi C5 A6 2.7T Quattro Twin Turbo
- Audi C5 Allroad 2.7T Quattro Twin Turbo
- Compatible K03 turbo applications
- Compatible K04 turbo applications
The valve design may also be suitable for additional compatible Audi, Volkswagen, Saab, Porsche and other turbocharged applications. Always compare the valve dimensions, hose connections and operating configuration with the original valve before ordering for applications outside those specifically listed.

❓ AUDI 2.7T DIVERTER VALVE FAQ
How many diverter valves does the Audi 2.7T use?
The 2.7T Twin Turbo configuration uses two diverter valves. That's why this XS-POWER listing includes TWO valves as a matched pair.
Will these fit a B5 Audi S4 2.7T?
They are designed for compatible B5 S4 2.7T Twin Turbo applications. Always compare the original valve connections and configuration before installation.
Will these work on a K04 B5 S4?
These valves are designed for compatible K03 and K04 2.7T configurations. The appropriate spring configuration should be selected according to the individual vehicle setup.
Are these blow-off valves?
These are primarily recirculating diverter / bypass valves, not conventional vent-to-atmosphere blow-off valves. They are designed to redirect discharged boost pressure back into the intake system.
Are these made from plastic?
No. These XS-POWER valves use black aluminum bodies for a performance-oriented, reusable design.
Why does the Audi 2.7T need two valves?
The Audi 2.7T uses a twin-turbo intake system and employs a diverter valve for each side of the turbo system. This listing supplies both valves required for the compatible dual-valve setup.
