Ford Fiesta ST BOV Block Off Plate

When it comes to horsepower mods, MAPerformance knows a thing or two. Thats why we've designed a Fiesta ST BOV Block off plate that will allow for the removal of the compressor mounted factory diverter valve. But why, you ask?

Plugging and sealing the factory Fiesta ST diverter valve will set you up for future mods, including the mounting of a new, higher volume/higher pressure BOV elsewhere in the charge pipe system. When making any kind of performance enhancing mod, you should always consider upgrading the BOV/BPV, and this is ever more true with the Fiesta ST. Not only is the factory placement unstable for increased boost, you'll also risk ruining the weak, brittle little BOV.


  • Made from high quality stainless steel
  • CNC machined for precise fitment
  • Stainless steel mounting screws for lifelong fit
  • Rubber seals help keep the boost in the charge piping


  • 100% Direct Fit
  • Made in the USA
