Fwiw, and for fun, my first time to cut open and personally view and share w/random pics of the MOPAR MO 899 oil filter:
• The outer case of the oil filter looks and feels durable until it is cut open, then the case is rather thin.
• The base plate is heavy and has large eight inlet holes and a beefy gasket, probably the only two good things.
• The anti drain back valve is thin/flimsy and is odd looking, probably due to the by-pass valve being at the top instead of the bottom.
• The by-pass valve is at the top and and has an internal spring/valve that is one piece with the core inner tube. Also, I don't know what psi rating it is for it to open.
• Filter media looks and feels like some type of cellulose fiber/paper and is glued together, not crimped and can be easily torn. There isn't any metal wire backing on the filter media.
•The inner core is fluted and doesn't seem to look restrictive.
• Don't know why there is the "leaf spring" at the bottom of the filter, the by-pass valve is internal in the filter core and at the top.
• There's no indication of whom manufactured it. It does quote on the oil filter that it's made in the US, 2023 FCA US LLC, all rights reserved.
Well, I've might of missed something, but imo, this oil filter is just "basic, get the vehicle off the assembly line" low oci oil filter ... I can't believe that I've used this oil filter religiously in the past, good thing I changed the oil filter at every three thousand miles, because that's most definitely looks to be of it's limit.
