I found a thread from 2009 that discussed this and found out that BMW has an OEM fog support that has an open area for air flow to the oil cooler. The part number is 51118043230 as seen on http://realoem.com/bmw/showparts.do?...51&fg=15&hl=34.
This can be ordered from Tischer for $4.91. I highly suggest that you order this if you have a factory oil cooler. Your other option is to take a dremel or razor blade and cut a hole in the fog support supplied by JGMods to allow air flow.
It is ok that the driver side is blocked off as the OEM ducts pulls air from the center opening for the brakes. Here is a picture of the passenger side opening with the OEM fog support. Hopefully this helps you guys out!
