Hey guys! PERM Tuning is the original upgraded PCV plate, originally designed and sold before the Focus ST ever came out but revised it to fit the Focus as well. PERM's latest revision is almost a complete redesign and the changes are pretty awesome. Here's the run down.

New Features:

  • Incorporation of factory PCV valve
  • Billet aluminum banjo bolt and fitting
  • Low profile outer edge, reuses factory bolts
  • New Perm Tuning logo engraved
  • Available in raw aluminum finish

Just to be clear, would the second port(banjo fitting one) need its' own dedicated catch can or would it be able to be plumbed into the same can, utilizing a check valve on the second port?

Sorry for the late reply! Yes, you can do that if you want. However, unless you have the intake manifold blocked off and the catch can is vented, it's not going to be much benefit. We don't recommend doing that anyway. The beauty of the Perm plate is really in running a 2 can system where you can vent crank case pressure from 2 places instead of just one during WOT and still retain vacuum during idle and part throttle. There really isn't a point to routing both ports to a sealed can connected to the intake manifold. That's not when too much crank case pressure is being generated so it doesn't benefit you. But can you do it? Yes.
