I fitted a K&N oil charged filter to my 2002 4.4 (with lpg) in 2007, recharged it once, it seems to do the job ok.

over the years with messing around with filters i have settled for just buying a good quality paper one now, for my x5 i use nothing but mann filters which is what bmw use anyway and always buy them using the mann part number rather than for a specific vehicle as then you avoid the good ole bmw mark up factor ..

It sounds pretty normal in day to day driving, but when you put your foot down everybody knows you have. I have kept the normal pipe that takes the outside air to the standard airbox and it now puts outside air into the area that the CAI draws in.
There’s lots of debate about drawing hotter/cold air in and I monitored air intake temperatures at the AFM before and after conversion. After 20mph the temperatures were the same and below 20mph and idling/traffic jams the temperatures were 2/3 degrees hotter.
