Just thought I'd run this by everybody, did an air filter change on my 2007 SLK55 AMG P30. Put in some new AEM dry flow air filters which have no oil in them, was always a K&N fan but their so loaded with oil thought I'd try something else and got a deal on Ebay. I encountered something that I have not found any information about. Came across "Post Air Filters" that look like cabin air filters. So I took them out considering I probably don't need "Post Air Filters", if anybody has any advise about this please chime in. Pictures are in a sort of DIY timeline.
Thank You

 

Are you saying the yellow oems were in with that other brand in pics 3,4 n 5?

 

Yes... the yellow oem are Mann and the gray this ones are Mann as well... Theres a housing that holds the gray ones real snug, had to mush the gray ones to get them out. I have seen the housings for the gray ones(With no gray filter) in your posted youtube video about the white SLK55 DIY. Also V6 SLK's have a similar air box but they do not have the housings for the gray filter... I'm so confused....

 

no need to be confused

this is what it was supposed to look like

 

So these post air filters are necessary? I would like to replace them but the P/N is not coming up anywhere.

 

I take that back, the white 2006 SLK55 in the youtube video did not have the housings for the "post air filters" in the air box.

 

True...i'm trying to find u the correct pics for what is there
I have a SC so don't have the AMG airbox anymore

 

That is strange, The gray filter housing is in the large main air box. I may try to "pop" them out. I did try to pry on them a little bit but it started cracking so I stopped. Are those the "Green" filter you have installed? The AEM ones I put make a nice sucking sound now, LOL. Going to drive the car tomorrow and see if there's a difference.

 

I have yellow oem mann filters
That is not pic of my car
I have a supercharger and air filters are changed differently.

 

Air filters under the "AMG' badges

 

Wow, nice. Just read your S/C adventure thread. So they put SL55 air boxes on which looks factory.... Very nice. I really want the Kleemann carbon fiber air box, but WAY to pricey...

 

you read all 17 plus pages of my thread? You must be a speed reader
