Back in November we bought a new to us gently used Ford Explorer for the wife. I also happened to buy a very used high mileage 2018 F-250. Today I finally got around to installing the filter minders for the engine air filters. Easy peasy. I love nerdy stuff like this. Both vehicles have a fomoco air filter in now. I put the truck one in myself. I'm not sure if the dealer replaced the filter back in November or not. It's a Ford one but it has a bunch of crap in it already so I'm gonna replace it to get a baseline.
