You can choose whatever oil or filter you want as long as it respect the compagny sp?cifications, but let says you get a faulty filter and you blow your engine, if they prove that it is the cause of the failure in my experience they are going to charge the repair and after that it is up to you to sue either the shop that install it or the filter compagny. So i personnaly prefer to put oem product, that way it,s ford fault if something bad happen..lol..
My opinion.
