What is the main benefit of the HKS Super SQV 4+RETURN KIT?

The primary benefit is improved turbocharger response, meaning your turbo can spool up faster when you accelerate. It also provides a distinct, satisfying sound when you release the throttle.

Why does this kit include a recirculation feature?

The recirculation feature sends the vented air back into the intake tract. This helps prevent issues with the mass airflow sensor and can contribute to a smoother idle compared to a vent-to-atmosphere valve.

Is this kit CARB approved for California residents?

No, this HKS Super SQV 4+RETURN KIT is not CARB approved and cannot be shipped to California.

Product Details

If you're looking to get the most out of your turbocharged Subaru GRB or GRF, the HKS Super SQV 4+RETURN KIT is a solid option. This kit replaces the factory bypass valve with a more responsive unit, which can help your turbo spool up faster and give you that satisfying blow-off valve sound when you lift off the throttle. It's designed to work with the specific boost pressures and airflow characteristics of these Subaru models.

The Super SQV (Super Sequential Valve) design uses a unique dual spring system that ensures it only opens under specific conditions, preventing premature boost leaks while still providing a crisp sound. This particular kit includes the necessary components to recirculate the air back into the intake system, which is often preferred for maintaining smooth idle and preventing potential issues with the mass airflow sensor. The construction is well-built, typical of HKS products, meaning it's made to handle the heat and pressure found in the engine bay.

When installing this, you'll want to make sure you have the correct tools and a good understanding of your vehicle's intake and vacuum lines. It's a direct replacement for the stock valve, but proper routing of the vacuum lines is crucial for it to function correctly. This kit is a popular choice for GRB and GRF owners looking for improved turbo performance and a more engaging driving experience.
