Der neue Deckel ab 2004 ersetzt die notwendigkeit der Feder im Deckel. Das Gehäuse muss dafür nicht gewechselt werden.

Hab grad die Kommentare des Artikels gelesen..
Die Vermutung stimmt also.. laut Mini Mania:

Does the updated cannister cover (post 7/2004) fit on a 2003 Cooper so that I can eliminate the spring and plastic cage in future oil changes?

Mini Mania: Yes, just get the newer cannister cover.

I've seen this article several times but it still doesn't say if you can put a newer housing on the 2002-2004 car. The goal is to get rid of the plastic cage and spring.

Mini Mania: Article edited for clarification - "YES, you can use the later cannister cover with the earlier base."
