At 95,000 miles, the whole cooling system should be replaced, not just those two plastic pipes. In accessing them, you have to remove so much. I have studied out replacing the cooling system on my Z3 1.9L, using RealOEM.com. You might do the same for your 2.5L, whose parts will be completely different. Put the last 7 of your VIN into RealOEM, save the link, and it will be easy to go back and navigate for your car. Here's my 1.9L. RealOEM gives typical prices and is not a store; BMW dealers are much higher, and stores like BMW South Atlanta and Bavarian Autosports will be less.

EDIT: I don't know if a 6-cylinder even has the plastic connector on the rear of the head.
EDIT: RealOEM typical prices total to $800. A BMW dealer could be many times that, while online vendors will be less than that.
