2021 F550 cabin air filter

just to share the process that I do may not be the process that the professionals do. but it works for me and I get to see exactly what I'm doing. I have put it in without taking out the owner's manual shelf but it bends the filter into a taco and too many times you break the air filter cover. this will cover most of the newer Fords 2019, 2020, 2021, 2022. f550 f450 F350 F-250 they all have the same at least that's been my experience. okay back to work!
