Our latest Kompact SmartPort explicitly made for the 2015 WRX, features the innovative new Smart Port drive-by-wire friendly staging technology that gives you the response of a Plumb Back valve with the high-performance benefits of a vent-to-atmosphere valve. The SmartPort system involves a new manufacturing process, utilising specialised alloys and coatings and a revolutionary new vent-to-atmosphere trumpet design. These unique designs allow for a swift response while providing enhanced sealing. The result is quicker spool-up and better performance on modern drive-by-wire vehicles.

Smart Trumpet Design 
Turbosmart’s SmartPort trumpet allows a softer spring in the body of the BOV to aid in valve response to the Plumb Back Port while still retaining the ability to vent to the atmosphere.
