Not sure why you would need to change it.
They can be checked however. Remove the PCV valve and shake it. If it rattles it is good. If it does not rattle it may be dirty with oil and other residues. Either way, if it is removed, soak it in some throttle body cleaner to remove the residues. Evaluate it again and if it works (rattles) re-install.
Or you can simply install a new one. I try not to throw away the OEM stuff since it is usually of pretty good quality. They are a pretty simple but effective device.

Separator Case part# check
Most sites show a match for MY 2011 but some are showing not.
My valley plate repair is in-process, and after seeing the inside of illwillem's, I want to replace this part.
What purpose does the foam insert serve? Anyone happen to know the part number?

The foam is for noise reduction only, and there's still plenty of DI noise that gets through. I wouldn't bother replacing it unless it is chunking. Mine was fine at 180k miles+ when I did my valley plate. Not sure why you'd bother with replacing the separator case. If you're worried about it (I wasn't in the slightest), rinse it with solvent and call it a day. It's not that critical, and in service it stays exceptionally clean inside from a contamination perspective.
