Give your BMW that distinct blow off valve sound while also holding more boost pressure with the Turbosmart Kompact Dual Port Blow Off Valve. The Turbosmart Dual Port Blow Off Valves are designed to install directly into your stock diverter pipe, for an easy installation. This blow off valve system is specifically for the BMW N54 engine where other blow off valves are universal. The Turbosmart Kompact Dual Port Blow Off Valve is an ideal upgrade for anyone who is running higher boost (software or tune) and a necessity if you would like greater boost response and no boost leaks.

    • Improved boost response
    • Gives your BMW that desired ""woosh"" BOV sound
     • Bolt on installation, connects directly to your OEM diverter pipe  
    • Replaces the factory plastic valves
    • No more boost leaks!
    • Can be used as a fully recirculation BOV or atmospheric vent
    • Fits all N54 equipped BMWs
    • Includes everything necessary for installation

Fully Recirculation  vs. Atmospheric Vent
The Turbosmart Dual Port BOV can either be configured as a 50/50 (progressive porting give early valve lift recirculation and later valve lift vent to atmosphere), fully recirculation BOV or 100% vent to atmosphere. Your N54's stock system is a fully recirculation design that ""recycles"" the blown off air back into the turbo. The recirculation design does not provide that ""woosh"" BOV sound, but still will provide you with all the other benefits of upgrading your BOV. The Turbosmart Dual Port system includes a special blanking plug allowing you to set it as a 100% atmospheric vent, where the blown off air will vent to the atmosphere and will produce that ""woosh"" sound.

Turbosmart Dyno Charts
The Following dyno chart was completed using a 1M, ONLY changing the stock diverter valves to the Turbosmart Dual Port BOVs. The graph shows the stock diverter valves leak boost, especially down low where it counts. Just by switching them to the Turbosmart Dual Port BOVs gains in torque are realized throughout the RPM range, with gains of over 25 Ft./Lbs down low.

The following dyno shows manifold pressure, and how just by switching to the Dual Port BOV boost pressure is maintained.
