Okay, so the filters will be OEM paper???? If yes, I will want to purchase K&N panel filters. Would I order them for a C320? . . if so what year range or model #? If no, what year and model MB would I need them for? Sorry to be a pest, but I have a 320 SLK air box that looks nice but provides no real benifit. I also have a 3.2 litre MB engine cover to use with a CAI but it's the one with the oil filter hole that doesn't quite line up. I just want to make sure I get it right this time around. Thanks ahead of time.
