The Turbosmart Kompact EM Series Plumb Back Valve (VR9) is a genuine plug-and-play upgrade for BMW turbocharged engines equipped with factory electronic diverter valves. Designed for maximum performance and reliability, the EM Series uses Turbosmart’s award-winning Boost-Balance Valve technology and proprietary onboard solenoid system—removing the need for reference hoses, external solenoids, or extra components.

Built from billet aluminum and engineered for full OE integration, this diverter valve delivers faster response, superior sealing under boost, and longer service life compared to factory plastic valves.

Key Features:

• Plug-and-Play Fitment – No adaptors, hoses, or additional wiring required

• Boost-Balance Valve Design – The more boost you run, the better it seals

• Integrated Pressure Control – Patented solenoid and pressure routing inside the valve

• Billet Aluminum Construction – Durable and heat-resistant with high-temp O-rings
