I saw that one also Malc, the main issue that I have is that I am parking my coupe in a common garage in my condominium complex where they discourage any maintenance being performed; so I purchased a Topsider oil changer and with the design of the aforementioned filter housing I would be able to sneak an oil change with not too much attention. I am hoping to find a place to do work in the near future but this will have to do for now. By the way I have seen this housing on RealOEM.COM for various engines with fittings for an oil cooler, I am concerned about Peter's comment about the oil passages though it looks like the E32 has the older block.
