Turbosmart Kompact Dual Port BOV Kit BMW 135i/335i/535i/Z4 w/ N54 Twin Turbo 3.0L 2007-2011
The Dual Port BOVs are a great way to vent some satisfying noise between shifts outward from your N54 engine while still recirculating some air for good efficiency. Block off plates are included so that you can convert to full recirculation should you ever want to. The silicone vent hoses ensure a leak free seal and a long life. Each dual port kit comes with two BOV's and everything you need for a complete installation.
