We know the glue has made it through the engine to the drain pan. No doubt VVT screens are catching it…..
Mopar Oil Filters from the Mopar store

It's OK if you are fooling yourself thinking the car manufacturers are really constantly monitoring the quality of their OEM oil filters. They aren't to the level you believe. Cut open filters posted here proves that. Like @GW. mentioned earlier, many OEMs were contacted about quality issues, and they act like it's the first time they ever saw or heard anything like that. Don't care what you or anyone else use ... this discussion is for others to see and decide what to use. People who read this forum a lot know what filters have good constant manufacturing quality and which ones don't.
Do you have any specific data on the Mopar oil filter for the 5.7 or are we still generalizing?
If you’re buying MO-339s, they’re cheaper on eBay. I got a dozen last year for $79, shipped. 2024 date codes.
Looks like the Mopar filters also suffer from the black glue of death and tearing media. Classic Purolator/M+H problems.
Howdy fellas,
Mopar MO-339 (04892339AB).
In service on a 2021 Ram Rebel 5.7 non-E torque for 6 months/4,500 miles. Valvoline Extended Protection 5w20.
ADBV was pretty stiff. The end caps were glued on solid and wouldn’t budge when pulled on. The media was decently straight BUT as can been seen had a tear in the pleat next to the seam. Im assuming due to the large gap.
An EcoGuard with Valvoline went back on.
Had a helper today, my boy enjoyed it. Let him cut the filter open himself.

Do a search for them in this forum and see what you can find and glean from that. As far as efficiency, I'd bet they are around 99% @ 30-35 microns. Some people don't care about efficiency, but again a personal choice. You will probably find some cut open posts too.
If I ordered a case of filters made by a company with sketchy quality, I'd cut one of the new ones open to inspect, as the filters in the case would most likely have been made on the same production run.
Edit .... looks like @GW. found an example. Looks to be the typical Mann+Hummel torn media issue.
Side note - and just because an oil filter looks good when inspected new, it doesn't mean it can't do something like tear the media or shed glue in use.

Thank you but I don’t buy car parts on eBay. There are counterfeits and believe it or not uncommon for a lot of the bulk merchandise to be stolen.
I am going to reach out to Stellantis today and show them this thread and indicate their oil filters are inadequate. I am sure they will respond soon, might even thank me - I can get a coupon for the unnecessary dealer upsell services.
TGIF to the rest of the folks who may have found the price information useful, have a good weekend.
I buy lots of car parts on eBay. From reputable sellers with long, positive histories and good return policies. I haven’t bought any fakes yet, and I have no reason to believe they are stolen. Sellers with tens of thousands of transactions over decades.
FWIW, I don’t run those filters on my Hemi because I don’t find them to be worth $10+. There are people, though, who insist on OEM filters. I keep them on hand to sell with the oil-and-filter deals I frequently sell/trade. I was simply trying to help you find the cheapest filter possible if you wish to run a Mopar filter.
Good luck.
I appreciate what you are saying. eBay has gotten better policing this type of thing so I believe you, but it is more of an issue than people realize. Particularly on Facebook marketplace, Craigslist, etc. For me I simply have better options in terms of convenience and wait time typically so it is not somewhere I go for auto parts. But again thank you for trying to be helpful.
Here is a MOPAR filter off my wife's then Jeep Renegade and was the factory installed filter. Made by the same people that made the Motorcraft.

OEM is not a guarantor of filter quality
Yikes. Tearolator special.
I understand your perspective but if it were me then, I just would avoid the brand. Not saying there aren't better alternatives but the original part (not OEM, the two are not the same) should be sufficient. Quality is a process and a discipline, it's not random.
Perhaps I am colored by the fact that my first car was a project BMW, and the factory BMW parts have always been excellent.
Have a good weekend.
