Turbo XS 08-12 WRX 50/50 Hybrid BOV

TurboXS releases the first Hybrid Blow Off Valve!. 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.
