HKS Super SQV4 Blow-Off Valve Kit with Recirculation injects a surge of performance and functionality into your 2002-2007 Subaru Impreza WRX, 2004-2007 WRX STI, or 2004-2007 Forester XT. This meticulously crafted kit incorporates HKS's industry-leading sequential blow-off valve design, ensuring exceptional performance and stable operation across a wide range of boost pressures.

Engineered for Peak Performance & Hassle-Free Installation:

• Sequential Blow-Off Valve Technology: The Super SQV4 utilizes HKS's pioneering pull-type, sequential valve structure. Unlike typical push-type valves requiring specific spring load settings, the SQV4 operates efficiently at any boost pressure without leaking, maximizing performance.
• Improved Boost Control: By effectively purging excess boost pressure between gear shifts, the SQV4 helps maintain optimal turbo spool-up and reduces turbo lag, maximizing overall performance and protecting your turbocharger.
• Recirculation Functionality: The included recirculation kit ensures that excess boost pressure is re-routed back into the intake system, maintaining proper air-fuel ratios and preventing potential check engine lights.
