they are the same, if i remember correctly

the newer ones have rounded corners and the older ones have straight edges, no difference if you ask me

REPLACEMENT AIR FILTER # 33-2859

You are right. Mine and the '04s are the same??

JAY55

Thanks, I was worried for a minute. My first internal mod snorkle and filter, hope it will give me a little HP gain.

jangy

snorkel? what snorkel?

MNG

i believe the snorkle mod is switching the stock plastic pipes that connect to the airbox from the grill area with the larger one from the S or SL class

where can i Get these filters from for the 2006 E55...where can I ordere them...any1 know a part number....i need 2 filters right?

JAY55

I assume you have an 06 model then the part # is 33-2859. Dean62 had a good advice, he bought the exact passenger side one and replaced the driver side with that. I went with the same route instead of getting the SL snorkle, I heard the SL one doesn't fit very well.

Dean62

Yes you need 2. I ordered them direct from K&N. Here is their web address....http://www.knfilters.com/. Check them out.

As a secondary place, I just ordered them yesterday off www.autoanything.com. They were in stock, about $4 cheaper and free shipping...Yep, I bought a 90k car and I'm worried about $4.

Be careful with the part numbers. 04s don't fit properly in the 05. Check with K&N on exact number before ordering from another supplier. From experience

Is this the 'green filters' you guys are talking about? is there any gain(im assuming very very minimal) from doing this if i currently have no performance mods? i know i will eventually want to change the filter anyways when i pull the trigger on the performance mods but is there any reason to do it now? any idea on what the part number is for an '03? and how easy is it to swap out myself? thanks guys.
