I've got those covers and had to use the breathers that are angled to keep the oil from leaking out. U can get them anywhere but I got mine from Cottons Performance.
You can just use a pair of the stock breather elements in both holes. You know...like the one that was used on the stock passenger cover that originally had the elbow and line connecting to the turbo inlet bell? Some of the parts stores still stock them and they are cheap. Do yourself a favor and pull the grommets out and cut out the rubber "steps" on the inside. They are supposed to keep oil splash down but according to a very reputable engine builder, they only cause restriction in air flow.
While you're at it, you can relocate your PCV like so:
Thanks for the replies. I changed out the baffled grommets and put some Mr. Gasket breathers. Works great.
Now i will order some that look like they belong on my car.
