Specifically designed for MY 2002 and up Subaru WRX and STi's, the WS-RBV requires no adapter kit to install. It is designed for people who want to run high boost levels, but still vent their BOV back to the air intake to maintain maximum driveability.
Under high-boost applications the factory bypass valve can leak, resulting in a loss of power. This valve is a heavy-duty, bolt-on replacement for the standard factory bypass valve. It has been CNC-machined from billet aluminum and brass to ensure years of trouble-free operation.
This is the perfect choice for WRX and STi owners looking to upgrade from the factory bypass valve, but do not want the attention-grabbing power of a blow off valve.
