The Turbosmart Kompact SmartPort Dual-Port BOV for 2015+ Subaru WRX is a drive-by-wire friendly upgrade that blends plumb-back response with vent-to-atmosphere benefits. The SmartPort system uses specialized alloys, coatings and a new trumpet design to improve sealing and response, helping quicker spool-up on modern drive-by-wire vehicles. Dual ports provide quieter normal operation and full venting under race conditions.
