On a sidenote.......can you provide a current RAM/Cummins approved or unapproved filter list???
I am not aware of an "approved" list of filters for any FCA products. There was a TSB many years ago concerning the filters coming apart and plugging the cooling jets. A manufacturer cannot specify you only purchase replacement filters from them. So if you look in an owners manual there will be the specific filter listed for the engine. If the filter you are using has a cross reference or application that matches the one in the owners manual you should be good.
There are many quality filters out there, but personally I have only run Mopar filters in everything I have owned. To me saving a couple of dollars isn't as important as the life of the product. I have never had an oil related failure, but there are not very many in the Cummins line even not using an OEM filters.
To me it makes sense to run what makes you happy, as long as it is obtained by a reliable source. That gets a little more difficult with online purchases, and if you look on DealerConnect, Mopar still has a means to report counterfit products, so they must be aware that there are those out there willing to take advantage of you at any cost.
