From their catalog, it appears that the 'red' one is the oiled filter and the grey/black one is the non-oiled. Mine came with the 'red' one. It seems that the latter (grey/black) is designed to be used with the sock. Would it be safe to assume that it comes from the factory pre-oiled and that they know how to dole out just the right amount?
It's my assumption that the oil/MAF issue arises when home mechanics (such as myself) try to clean and re-oil the filter and overdo it - creating the MAF mess. Though I have oil-based K&N filters on my other cars that I plan to clean and re-oil, the Porsche is a $100K sports car that is very CEL trigger happy so I plan to just buy a new one (about $79.00) each time. When that arises, the question is which one to get?
Am I getting all this right?
And thanks,

If you have the oil base one-recommend you buy the filter sock and avoid the oiling. You can always remove and clean the filter
