BMW N55/N63 Turbosmart VR9 Dual Port BOV Review w/GOOD SOUND!

Back from the dead. I had the Turbosmart Kompact EM VR9 Dual Port Blow-Off Valve installed on my BMW 640i... and I love it. Watch and listen to how it sounds, also why you should have a pro install it for you if you don’t have a lift. BOV link -
