I have used all 3 but are those brands good to use? for my porsches?
thanks.

 

I just looked into this last night for myself. There didn't seem to much information on Cayenne owners straying away from OEM. Much of the information I got was in reference to 996 and 997 owners.

The consensus was that Mahle and Mann are both top notch and at one point may have been OEM manufacturers for some p-car filters. WIX is also a great filter that is supposed to have better-than-OEM filtration.

I ended up buying a WIX filter.

Hope this helps.
