Description
The HKS Universal Racing SQV Blow-Off Valve provides a blow-off valve configuration for managing charge-air pressure when the throttle closes.
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.
Technical details
- Manufacturer part number: 71008-AK004.
Application-specific requirements
- The flange must be welded to a pipe.
- Installation flange is included.
- A piping hose is not included.
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.
