Changed air filters on the BMW 750iL. It is a big car, but the M70 V12 is still wedged into the engine bay. Took an hour or more to change them, plus I had to drive probably 25+ miles round trip to actually get the filters.
The process is straightforward enough, but a couple of the clips have rather limited clearance. Thought I was going to end up pulling the intake plenum, MAF, and air box for both sides. I finally obtained barely enough clearance by disconnecting the MAF wiring on one side and moving the MAF wiring on the other side. Still ended up with a blister and a cut, though.
I suppose my next my project is changing plugs, which will probably be a four to eight hour job, assuming I even attempt it. I might just take it to the local import shop instead.
