There is a cabin air filter listed in many filter catalogs. If you read the small print it says that an optional kit (it gives the part number) from Ford is required. If you call Ford with the part number you will find that it was discontinued before the SD was ever in production.thallanor Discussion starter. 3 posts · Joined 2009. #1 · Aug 21, 2009. I was wondering if someone would be able to point me in the general location of the cabin air filter, if the 2005 Ford Excursion was equipped with one - or where it is supposed to go if it is capable of having one added, but one not installed, as I've seen Ford do on some ymmRE. 285 495 157 67 427 175 95 37 309
