I agree, for the NA cars, no issues, but for the Turbos, use Porsche branded filters.
That combined with check valves on the turbos, and possibly p-trap type scavenge lines, should clear up any oiling issues with the Turbos.

you are very lucky in this regard, I have not seen any cars that have not at least puffed sometime during startup, even if only once every couple of years. Your car is unusual.
Maybe time for a survey!! :-)

Thank you for the clarification sir. 
Leaking/smoking issues seems limited to the turbo cars. I ran the Mahle/Mann filter as supplied by Autohaus on my '96 C2 the entire time I had it and never had a leaking/smoking issue, ever. However, I had some leftover from owning that same C2, so I used them on my turbo......now it'll leak and smoke a little if it sits too long. This is the reason I bought the OEM units from Sunset.
Personally, I think the Mann or Mahle filter are perfectly fine. There is just something about the check valve design (that was fixed in the OEM parts and not the aftermarket parts) that the turbos don't like.
