What does a recirculating blow-off valve do?

A recirculating blow-off valve, like this Turbosmart Kompact Plumb Back, sends excess boost pressure back into the intake system. This helps to protect the turbocharger and maintain boost pressure between shifts, but it does so quietly without venting to the atmosphere.

How do I know if my car uses a Bosch or Denso bypass valve?

You can typically find this information by inspecting your vehicle's original bypass valve. If you're unsure, consulting your vehicle's service manual or a trusted mechanic can help identify the manufacturer of your factory bypass valve.

Can this blow-off valve be shipped to California?

No, this particular blow-off valve is not CARB approved and cannot be shipped to California due to emissions regulations.
