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: 2008–2010 Subaru WRX / 2005–2006 Subaru Legacy 2.5 GT.
Design and operation
The Super SQV uses sequential valve operation and a pull-type relief mechanism. Differential pressure controls valve movement as the throttle closes, allowing the valve to manage pressure release across changing boost conditions. A return arrangement recirculates the released air into the intake, so its configuration needs 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.
