Turbosmart Kompact EM BOV VR9 Dual Port

Stock diverter valves leak under pressure and respond like molasses when you need instant boost retention. The Turbosmart Kompact EM BOV VR9 Dual Port delivers pressure relief that's 57 times faster than your eye can blink, giving you the throttle response your BMW's turbo was designed to deliver.

Performance Gains

Expect immediate improvements in throttle response, especially during rapid gear changes where stock diverter valves create lag between shifts. The dual-port design vents excess pressure to atmosphere for audible turbo flutter while recirculating enough airflow to maintain proper MAF readings and prevent rich running conditions. You'll notice sharper boost retention at part-throttle and cleaner transitions between gears, particularly beneficial for Stage 2+ builds running higher boost pressures where stock valves become the weak link.

Installation & Supporting Mods

Direct bolt-on replacement for most BMW applications using the factory diverter valve mounting location. Installation time depends on your mechanical ability. Professional install recommended. The EM (electronically controlled) version maintains compatibility with your DME's boost control strategy while delivering superior flow characteristics. We have installation videos available for most common BMW platforms. Need help planning your build or stuck mid-install? Text us at 813.252.1025 — we will walk you through it.
