07-11 BMW 335/335i Turbosmart Blow Off Valves

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.

The Turbosmart Kompact valves are designed as direct replacements for the factory BMW bypass valves and offer quicker action, better flow and higher strength under boost. The Kompact series is also substantially smaller than other valves on the market, making installation a breeze in tighter engine bays such as that of your 135 or 335. The Kompact Plumb Back system recirculates all excess pressure back into the intake system. Great for those enthusiasts trying to stay stealthy but still want the performance and reliability benefits of a quality valve. This kit comes with two BOVs, durable silicone boost hoses, and all necessary installation components.
