Description The Fiesta ST180 GFB DV BOV alters the sound of the dumping/BOV that can be heard if an aftermarket intake is fitted. 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 DV retains the same recirculating configuration just like the OEM set-up. The dumping sound is usually best heard with an aftermarket intake like our Karter Performance Stage 1 Induction Kit. **Note: This may require a service (disassembly & clean) every now and then.
