TurboXS Hybrid Blow Off Valve Subaru WRX STI 08+

The Hybrid Blowoff Valve gives you the Blow Off Valve like ?Whoosh? while still recirculating a portion of the vented air back to the intake. This helps to keep your Mass Air Flow Sensor happy and reduce the annoying backfires that can happen with full vent-to-atmosphere blow off valves.

The Hybrid valve not only improves the look and/or sound of your 08 WRX/Sti, but it also helps improve performance. The stock bypass valve begins to crack open and bleed off boost pressure at around ~20 psi. Replacing your stock bypass valve with a TurboXS Hybrid Blow Off Valve will allow you to run much higher boost pressures and make significantly more torque and horsepower. Additionally, when the stock valve leaks, it makes your turbocharger and your intercooler work harder to make the same boost pressure. Replacing it with a TurboXS valve improves both your turbocharger and your intercooler efficiency. TurboXS valves have been race proven at boost pressures of 50+ psi to give you the peace of mind that that no matter how far you want to push your car for power, your TurboXS valve can handle it.

Designed specifically for the 2008 Subaru WRX. The valve features an innovative re-circulation and vent to atmosphere operation. It has been tuned to offer the best blend of vent to atmosphere and re-circulation without check engines lights, stumbling or the dreaded back fire issues that are commonly associated with Blow OFF Valves and turbocharged cars that use Mass Air Flow configurations. Each kit will bolt directly to your Subaru without any additional parts.
