Upgrade your BMW’s factory diverter valve with the award-winning Turbosmart Kompact EM Series. This Plumb Back VR58 is a true plug-and-play solution designed specifically for the third-generation B58 engine. By replacing the flimsy plastic OEM unit with a motorsport-proven billet construction, you eliminate common boost leaks and pressure failures. The Kompact EM series features a proprietary internal solenoid and patented pressure control, allowing for full OE integration without the need for external hoses or adapters. Thanks to Turbosmart’s Boost-Balance technology, the seal actually strengthens as boost pressure increases, ensuring your turbocharged straight-six maintains peak performance and lightning-fast throttle response in any driving environment.
