Description
The HKS Super SQV4 (Super Sequential Blow Off Valve) for the Subaru WRX VA uses a dual-stage sequential pull-type valve to vent excess boost pressure the moment the throttle lifts, preventing compressor surge across the full boost range from low to high. A differential pressure control system governs opening precisely without the spring-load compromise of push-type valves, and the triple-fin funnel produces the signature HKS induction sound.
Features
- Sequential dual-stage valve: small primary valve opens first for rapid initial discharge; large secondary valve follows for full relief at higher boost
- Pull-type operation - valve is pulled open by pressure differential rather than pushed, preventing leaks at any boost level
- Silver-coated aluminium die-cast body
- High-stiffness metal die-cast secondary valve
- Triple-fin funnel design for the characteristic HKS blow-off sound
- Optional Round Fin available separately for sound tuning
Fitment
- Subaru WRX VAG (VA chassis, 2015-2021)
Notes
- This is an atmospheric-vent (vented to atmosphere) blow-off valve. On vehicles with a mass airflow sensor, venting to atmosphere can cause running issues at idle after throttle lift - verify compatibility with your tune before fitting.
- JDM product: any HKS certification applies to the Japanese market. Check your state's regulations before road use in Australia.
