Description Wanting a unique blow-off-valve sound? The GFB VTA (vent to atmosphere) BOV might be for your Ford Fiesta ST180/200. GFB manufactures some great products with the philosophy of keeping what works, replace what doesn’t. The OEM plastic valve mechanism is replaced with CNC billet components that’ll last a lifetime and retains the factory solenoid system allowing for a lower total cost/part price. The GFB VTA differs from their DV by allowing atmospheric venting of the DV (diverter valve) / BOV (blow-off valve) under full boost. This way, the ‘dump’ is a lot more audible. **Note: This may require a service (disassembly & clean) every now and then.
