K&N Part # for 04 E55? TIA
Searched around, only to find out that there maybe different partnumbers for different years. 
K&N site says: 33-2181, but I read that this may not be the number that fits all models (2005 and up).
Any help is greatly appreciated.

2181's Will Fit
I had the same problem and went directly to K&N. After exchanging a lot of emails with K&N and their willingness to clearly demonstrate to me using an AMG airbox that the 2181 filter will fit I'm satisfied they do. I installed them and they work fine. I'm not sure if they make any performance difference though-

Ok... but yours is a 2005.

I asked K&N the same question. According to K&N the airbox is the same size for all 2003-2006 E55's. K&N is in the process of eliminating filter part numbers that overlap multiple cars. The 2181 filter is the same size as the previous 2586.

Really? Cause I read this from you and it had me worried:
I recently purchased a 2005 MB E55 AMG. Your website specifies a 33-2859 filter but, that has been recently discontinued. Instead you say the correct filter for an E55 with a 5.5L supercharged engine vs. the E/S500 with a 5.0L normally aspirated engine is now a 33-2181. YOU ARE WRONG! The 33-2181 is too tall and the filter housing will not seal correctly. Compare the dimensions of the two filters and you'll see there is a difference. Next time you think one generic filter size fits all do your homework! After many years of buying K&N filters for my BMW's, Porsche's, Shelbys and other high performance cars I'm switching to green filters and posting a copy of this email on all the websites I can.
