Turbosmart Kompact Plumb Back Diverter Valve
Fits Most Models
TS-0203-1222
Overview:
The Turbosmart Kompact Plumb Back Diverter Valve is a high-quality, full recirculating blow-off valve (BOV) designed to improve the performance and reliability of your turbocharged vehicle. Unlike vent-to-atmosphere valves, this Plumb Back system recirculates all excess boost pressure back into the intake system, maintaining smooth turbo operation and preventing compressor surge.
This valve is ideal for enthusiasts who prefer a stealthy setup without the audible venting sound but still want the benefits of a premium BOV. It offers enhanced drivability and consistent boost control, making it suitable for daily drivers and performance enthusiasts alike.
Note that twin-turbo applications, such as the Audi S4 2.7L (B5) from 1997 to 2001, will require two valves for proper operation.
Key Features:
The Turbosmart Kompact Plumb Back Diverter Valve combines advanced engineering with practical design to deliver reliable performance and seamless integration.
- Full recirculating design returns all excess boost pressure to the intake system, preserving turbo efficiency and preventing compressor surge.
- Compact size with 25mm fittings allows for easy installation in tight engine bays and compatibility with most turbocharged vehicles.
- Durable construction ensures long-lasting performance under high boost and temperature conditions.
- Stealthy operation with no venting noise, ideal for enthusiasts who want a quiet, factory-like setup.
- Requires two valves for twin-turbo setups, ensuring balanced boost control across multiple turbochargers.
- Designed to improve throttle response and maintain consistent boost pressure during gear changes and throttle lifts.
- Compatible with a wide range of vehicles due to universal fitment and standard 25mm plumbing.
Construction & Design:
The Kompact Plumb Back Diverter Valve features precision engineering with robust materials to withstand the demands of turbocharged engines. Its compact housing and fittings are designed for straightforward plumbing back into the intake tract, minimizing pressure loss and maintaining system integrity.
The valve’s internal mechanism is engineered to provide reliable sealing and rapid response to boost pressure changes, ensuring smooth operation and protecting your turbocharger from compressor surge. The 25mm fittings offer a versatile connection size that fits most aftermarket and OEM intake piping.
Installation & Fitment:
This diverter valve is designed for universal fitment on most turbocharged vehicles with 25mm vacuum lines. Installation involves plumbing the valve back into the intake system to recirculate excess boost pressure effectively.
For twin-turbo vehicles, such as the Audi S4 2.7L (B5) model years 1997–2001, two valves are required to manage boost pressure from both turbochargers properly.
No cutting, drilling, or special tuning is required for installation, making it a straightforward upgrade for enthusiasts seeking improved boost control and reliability.
- Fits most turbocharged models with 25mm vacuum line fittings
- Requires two valves for twin-turbo setups
- Simple plumbing installation with no permanent modifications needed
