Thanks flashtwosix! I get the difference between the m54 and m52 models, but still wondering what the cold climate version actually is vs the regular one.
EDIT: just heard back from getbmwparts.com and they say the only difference is that the hoses are insulated. I'm going with the cold-weather kit since my car does sit outside overnight these days.
