2015-2021 Subaru WRX / WRX STI Turbosmart BOV Kompact Dual Port TS-0203-1015

Dual outlet-type BOV. The Kompact Dual Port vents to the atmosphere and back into the air intake. Ports with sequential timing allow quieter operation during everyday driving while still offering the performance and sound of a vent-to-atmosphere BOV when the going gets more challenging.
