2005 Ford Focus "Lifetime" air filter swap with Gen 2 OEM filter assembly.

Did any check engine light pop up for you? I tried this a couple days ago, test drove it around and after a few minutes I got a system too lean code. MAF sensor was cleaned and reading fine, but seemingly somewhere down the line it was getting in more air than the car was expecting.

@Evan-cr3oh So far so good for me. There is another video out there that mentions the different emission vehicles, SULEV, PZEV, LEVII. Not 100% percent sure, but it looks like that May make a difference. Thanks for watching.
