BMW sells a Cold weather CCV "kit" with the main 2 hoses installed, I'm assuming because its probably easier for techs to replace as an assembly that way.

If doing it yourself though, buy the extra 2 hoses and the dipstick O-ring, insulated versions obviously.

And like I was discussing earlier with Gary, the OFHG (oil filter housing gasket) might be a good idea, as well as PS reservoir and hoses replacement (if leaking) while you are working on the intake manifold side. Also, you most likely will be unbolting the throttle body if doing the CCV, clean it out and put a new gasket on it, as well as clean out the ICV.

And don't forget to do a throttle body adaptation when you're done, or your car will idle like shit lol!
