This isn't a big deal but will probably note it when I take car in sometime. It's not worth a drive to the dealer over. The foam piece on the removable piece of air filter has separated and some of it is sticking to enclosure. Here are a couple pics.

 

As long as the filter media has no gaps or holes you are ok.

 

Same thing happened to me, on the driver side also. I guess I will add this to the list of things the dealer needs to look at when I take it in for service.

 

ditto, although on the passenger side.
