The Turbosmart Type 5 Dual Port Smart Port blow-off valve for the 2015 Subaru WRX uses drive-by-wire friendly staging technology to deliver the response of a plumb-back valve with vent-to-atmosphere benefits. Its redesigned piston and trumpet geometry improve sealing and response, aiding quicker spool-up on modern electronic-throttle vehicles while providing tunable venting behavior tailored to the 2015 WRX.
