This is a K&N CAI I purchased for my Crown Vic but for some reason it will not work with my 2011 no matter what I try. It is for the Crown Vic but sure it could be modified to work on a Ranger or any other vehicle that uses the card type MAF. I paid $300 for it brand new and installed on the vehicle twice. Asking $150 Shipped obo. Has all hardware from the factory. I'll post pictures of it when I get off work this evening but here is a stock photo.
