The Go Fast Bit BOV is a hybrid BOV that allows the system to be fully atmospheric or fully recirculated depending on what you're trying to achieve. If you want your BOV to make noise, this unit can be fine-tune to give you that atmospheric BOV sound without causing a CEL, stalling, or your WRX to run rich.

Besides the noise, why else upgrade the stock WRX bypass valve? The stock unit is known for leaking and having inconsistent boost pressure that will prevent your WRX to perform at its best. Moreover the GFB BOV can return the engine to peak boost up to 30% faster than the stock unit when shifting gears.

Overall its a great mod to have for optimal performance.

  • 2005, 2006, 2007, 2008, 2009 Legacy GT


Fully Adjustable from Atmospheric to Recirculated.
