Hello. I have a query regarding a Crosland pollen filter I purchased from ECP for a 2005 C180k. When I removed the current filter (original Mercedes) from the car and compared it with the croslands one I brought, there were a couple differences. Although the shape and size is the same. the side flaps that you fold back and also the foam/rubber on one of the edges to make it air right seem to be mirror imaged I.e opposite side when compared. So although the filter will fit, it won't be as per the original one I removed and also the filter surface itself will be difference I.e one side is darker than the other and again not as per original. I don't want to affect the air coming into the cabin. Has anyone else had the same experience?
