WHAT IS THE TURBOSMART KOMPACT EM?
The Kompact EM is a direct replacement for your factory electronic diverter. Factory valves rely on plastic components that can struggle under increased boost, repeated heat cycles and tuned-engine demands. The Kompact EM swaps the original assembly for a precision-engineered solution that delivers improved durability and reliable boost control.
These approved valves are Plumb Back models—boost pressure recirculates into the intake system just like the factory design. You get an upgraded valve with OEM-style discretion.
WHY UPGRADE YOUR FACTORY DIVERTER?
Modern turbocharged engines depend on the diverter to manage charge pressure when you lift off the throttle. A leaky or inconsistent valve can hurt boost recovery, throttle response and overall performance.
The Kompact EM delivers:
- Direct replacement for the original electronic diverter
- Precision-machined billet construction
- Plug-and-play electronic integration
- No spring changes needed for higher boost
- No ECU calibration required
- OEM-style Plumb Back operation
- TÜV approval

BOOST BALANCE TECHNOLOGY
At the heart of the Kompact EM is Turbosmart's Boost Balance Valve Technology. Conventional piston valves need heavier springs as boost pressure rises—but heavier springs reduce valve response and need swapping when you change your boost level.
Boost Balance Technology uses boost pressure to keep the valve sealed, allowing it to stay secure under increased pressure while responding rapidly to ECU commands. Whether your engine is stock or modified, the valve manages higher boost without requiring spring changes.
PLUG-AND-PLAY PERFORMANCE
Each Kompact EM is engineered for its specific application with correct mechanical fitment and electronic connection. It connects to your factory wiring and is controlled by the original ECU—upgraded valve hardware without needing a separate controller or ECU tune.
Always confirm the correct valve for your exact model, engine and production year before ordering.

WHAT IS THE TURBOSMART KOMPACT EM?
The Turbosmart Kompact EM is a complete replacement for the vehicle’s factory electronic diverter. Many factory diverter valves rely heavily on plastic components that can become vulnerable when exposed to increased boost pressure, repeated heat cycles and tuned-engine demands. The Kompact EM replaces the original valve assembly with a precision-engineered solution designed to deliver improved durability and reliable boost control.
The approved valves are Plumb Back models, meaning released boost pressure is recirculated into the intake system in a similar way to the factory valve. This maintains discreet, OEM-style operation while upgrading the valve’s construction and boost-control capability.
WHY UPGRADE YOUR FACTORY DIVERTER VALVE?
Modern turbocharged engines depend on the diverter valve to manage charge pressure when the throttle closes. A valve that leaks or responds inconsistently can contribute to poor boost recovery, reduced throttle response and inconsistent performance.
The Kompact EM range offers:
- Direct replacement for the original electronic diverter valve
- Precision-machined billet construction
- Plug-and-play electronic integration
- No spring changes required for higher boost levels
- No ECU calibration required for installation
- OEM-style Plumb Back operation
- TÜV approval on the listed products

BOOST BALANCE TECHNOLOGY
At the centre of the Kompact EM design is Turbosmart’s Boost Balance Valve Technology.
Conventional piston valves can require increasingly heavy springs to remain closed as boost pressure rises. A heavier spring can negatively affect valve response and may need to be changed as the vehicle’s boost level changes.
Boost Balance Technology uses boost pressure to help keep the valve sealed. This allows the Kompact EM to remain secure under increased pressure while still responding rapidly when the ECU commands the valve to open.
Whether the vehicle is standard or modified, the valve is designed to manage increased boost without requiring the owner to change springs each time the engine setup changes.
PLUG-AND-PLAY PERFORMANCE
Each Kompact EM is engineered for its intended application, including the correct mechanical fitment and electronic connection.
The valve connects to the vehicle’s factory wiring and continues to be controlled by the original ECU. This provides the benefits of upgraded valve hardware without requiring a separate controller or ECU calibration.
Vehicle-specific installation requirements can vary. Always confirm the correct valve for the exact model, engine and production year before ordering.
