Description The Ford Focus ST GFB DV is a complete BOV replacement for either your Focus ST225 or Focus ST250. If you’re wanting to upgrade your BOV/Recirc Valve, the GFB DV is the way to go. The DV recirculates just like the OEM unit. For those wanting a louder BOV sound look at the GFB VTA varient which vents externally allowing a much louder sound. The Ford Focus ST GFB DV features CNC-machined billet components that last a lifetime and cannot be damaged by high boost pressures or the associated increased charge temperatures. The DV allows sharper throttle response, solves boost leak issues and is built to last.
