I believe they all have said the car runs smoother too.
Add some E60 owners to that list as well. Mass hysteria or true occurences? You be the judge. All I know is that after 9 months and 12,000 miles of driving it, I can tell a difference since last night. MPG doesn't seem to be affected either BTW.
Added note: I've got a new filter on order that should be in Wed/Thurs. When I replace the filter I'm going to look and see if there are additional deposits, etc that I didn't see before. Yea I know that 4-5 days is not a long period but I have to take it apart again anyway for the filter change. I'll try to remember to take some pics.
