I got mine from Wilkinson. Chances are these are one of the parts he buys in bulk, once or so a year.
I was told that they have BMW part numbers but you are going to have to make friends with a BMW person that knows the line.
These are the ones I got from Wilkinson.
The internal cup, duct on the left one is 45 degrees. The right one is 90 degrees and I think he was missing something for the center one? I don't remember now?
The center one you need to make a sheet metal duct from the existing heater box for the center vent to sit into. It doesn't use a cup like the other two do?
Maybe I got the last parts he had?
The ducting hose itself we can get here in a general auto parts store. It is what connects the heat riser from the exhaust manifold to the air cleaner snorkel.
