Valvola Blow-off Turbosmart Kompact Smart Port Subaru WRX 2015+ - Black

Our latest Kompact Smart Port made specifically 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 Smart Port system involves a new manufacturing process utilizing specialised alloys and coatings, along with a revolutionary new vent to atmosphere trumpet design. These new designs allow for very fast response while also providing enhanced sealing. The result is quicker spool-up and better performance on modern drive-by-wire vehicles. Smart Trumpet Design Turbosmart’s Smart Port trumpet allows the use of 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 atmosphere.
