HKS Super SQV IV Blow-Off Valve Kit with Recirculation injects a surge of performance and functionality into your 2008-2014 Subaru WRX STI. 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 SQV IV utilizes HKS's pioneering pull-type, sequential valve structure. Unlike typical push-type valves requiring specific spring load settings, the SQV IV operates efficiently at any boost pressure without leaking, maximizing performance.
-
Improved Boost Control: By effectively purging excess boost pressure between gear shifts, the SQV IV 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.
