The HKS Super SQV (Sequential Blow Off Valve) is engineered for performance enthusiasts looking to enhance their Subaru WRX 4D FA20 (2015-2021). This innovative valve features a unique sequential valve structure combined with a differential pressure control system, ensuring seamless operation across a wide range of boost levels, whether low or high.
Thanks to its Pull-Type relief design, this blow-off valve maintains stable performance regardless of the boost pressure. It maximizes charge-response by efficiently managing pressure-charging and air relief when the throttle is engaged or disengaged. Designed specifically for modern turbocharged vehicles, the Super SQV guarantees reliable actuation, making it a perfect addition to your setup.
Users appreciate the noticeable improvement in throttle response and the aggressive sound that the Super SQV adds to their Subaru WRX. Many have noted that it not only elevates performance but also enhances the overall visual appeal of the engine bay.
