All that carbon filled used sump oil going through your intercooler and inlet manifold, mixing with all that soot also coming into the inlet manifold from the egr to form a thick solidified mud in the manifold isn't good. If you go for the prettiest most convenient option you'll wish you hadn;t when you have to get your intercooler, manifold and egr system
cleaned out or replaced.

As to the filter, you can buy an aftermarket washable and reusable filter on ebay for the provent.

Intake on both catch cans is the same, dry but some residue in joins, nooks & crannies.
