BITOGERS,
I have searched high and low and couldn't find cut open pics of the AC Delco PF64 or the AC Delco UPF64R oil filters on the net. I was bored at work today and decided to do a side by side cut open comparison myself and post the pictures. The UPF64R weighs more and has different internals, but the filter media looks to be of the same material, but just thicker and heavier duty. My car calls for the PF64 oil filter, but I am wondering if there is any harm in running the UPF64R oil filter. It looks to be constructed better.
Here are the pictures:
