Description
The HKS Super SQV IV Blow-Off Valve Kit provides a blow-off valve configuration for managing charge-air pressure when the throttle closes. Application: Subaru Impreza (GC8/GF8) / Subaru Legacy (BH5/BE5).
Design and operation
When the throttle closes under boost, the valve provides a release path for pressure remaining in the intake tract. A return arrangement routes the released air back into the intake, so valve and return-kit configuration need to match the vehicle’s airflow-measurement strategy.

Installation and selection
Check the factory or aftermarket intake layout and any required intercooler piping. Select the listed return configuration deliberately; a valve package and a separate return accessory are different products.
