The Turbosmart Kompact EM plumb-back blow-off valve is specified for 2022-and-newer Subaru WRX FA24F applications. Intended to replace the factory valve, the Kompact plumb-back version vents boost back into the intake tract rather than to atmosphere, matching vehicles that require recirculation. It provides an upgraded valve option for supported WRX models where that installation style is desired.
