GFB VTA Atmosphere Diverter Valve - Ford Fiesta ST/Focus ST (Mk8/Mk4) / Mercedes A-Class (W176) CLA-Class (C117) / Peugeot 308 GTi (T9)

GFB is an Australian designed and manufactured brand with a strong motorsport pedigree, and the VTA builds on the proven DV+ platform by adding aggressive atmosphere venting for genuine blow off sound.
