The Turbosmart Kompact Dual Port blow-off valve is a dual-outlet unit specifically made for Subaru 1998-2000 Forester and 1999 WRX applications. It vents to atmosphere and recirculates to the intake with sequential-port timing for quiet operation during normal driving while delivering vent-to-atmosphere response when stressed. The design balances daily drivability with the sound and benefits of an open BOV under load.
