Changing your factory diverter valve out for an aftermarket unit? You’ll need one of our BlockD™ Factory Diverter Valve Delete Plates.
This plate attaches to your stock or Borg Warner turbo to delete your stock diverter valve. This is essential when you are using an aftermarket BOV, so that your car doesn’t have two areas where it is releasing boost pressure.
Please note that this plate is included with all of our Focus ST Exhale™ BOV Kits.
