I’m running the same Fleetguard filter, same one that I purchased from Geno’s every service. I’m pretty sure I’ve got the MAF from china, that was one of the things I looked at. I just ordered another air filter from Geno’s ( the fleet guard ), maybe the one I got is over oiled and is causing a restriction. IDK. It happened right after my last service and the only thing I can think of that would cause me issues that I messed with is the air filter.

6.7 Engine Air Filter Confusion

I wondered if mine was going to go haywire after my last filter change but it didn’t seem even notice. I changed the TBAP sensor, the one in front of the MAF sensor, in September of 24 and later reinstalled all of the AGS vanes and it didn’t make any difference either. The last time I put them back in it immediately went into regen so I think changing that sensor helped.
What made you change that sensor? Is that the one that reads the barometric pressure? We live in the same climate and mine is at 29.5 most of the time. When a cold front comes through it might say 29.8 but doesn’t move other than that. What does yours read?

The new AF27684 looked more white compared to the old mopar filter that i had. When I replaced the new part # filter that my truck didn't like i snapped a Pic of all 3 to compare the differences.
Crappy new filter on left, new AF27684 in center, used, questionable over oiled mopar filter on right
I am kicking myself for not holding onto the air filter from this last service. Honestly I could have waited to change it as it clearly had more life, it’s just easier to keep up with to do it all at once. I’ll have to go look at mine when I get off of work but I wanna say the Fleetguard filter I bought is on the yellow side like the mopar one in your comparison photo. Fingers crossed the one I just ordered solves the issue.

Mine reads in psi not inhg. I would have to go look at mine but it does change depending on the barometric pressure and altitude. The old sensor that I took out only showed 15 psi and never changed while I monitored it. The new one has gotten down as low as 14.35 and has never gotten over 14.70 around here. It got a lot lower when we went to SLC last year. Down in to the 11’s. Where you are with it being pretty flat, elevation wise, I wouldn’t expect it to change much.
I just had service done at the dealer last week. The truck also needed a new air filter. I had asked them to show me the filter before installation. It did not have the glue strips. The service guy said specifically they use only the Mopar filter without glue strips. Are you saying there is a latest new version of the filter that DOES have the glue strips?

Yes. I’ll have to look up the number for it though.
Interesting. Just when even the dealers were saying to be sure not to use the filter with the glue strips, they come out with a new filter, with glue strips??
I have only a few miles on the truck since the service but I hope my regens stay at 24 hours. Hopefully I won't need another AF for a year or two and by then maybe this confusion noted in the title will be resolved.

Just one more instance showing that they don’t know what they’re doing.
That filter has glue strips in the picture at Geno’s, wonder if RAM decided it wasn’t glue strips causing issues but the oiling causing issues?

I personally think it’s something to do with the air filter housing but I don’t have the equipment to check it out. And the tuning.

I'm curious to hear how other 19+ trucks are responding to this new filter with glue strips, my truck hated it, but I have a '22 that seems to be more sensitive compared to other years.

Mine is a 22’ also.
It is confusing for sure. What is the consensus here today as to which filter is the one to use? Or is there really still just confusion and uncertainty and no consensus? I checked the invoices and last week and also previously the AF number shown on my invoice is 53034051AB. No other part numbers shown on the paperwork. Is the AF27684 filter the same one as 53034051AB?

It’s a conundrum for sure. The AF 27684 is what is in mine and it’s working. That’s the one I’ll use as long as I can get them.

And to add to the confusion:
Chasing down the ever common regen issues on my 2022 SO, and came across some info that some might find interesting.
Ordered the Chinese MAF sensor P/N 68444077AA. When it arrived, it came in packaging with the PN 68334657A, except it was the Chinese unit stamped ABMBV, and not the German unit stamped AARFN.
Thought a heads up would benefit those tracking down the “correct” MAF for their vehicles. I attached pics of the packaging my new unit came in.
Cheers.

Very interesting. What he says makes sense and he sure says it like he is sure it is correct. But I have not had any issues at all so far with the "oiled" filter without the glue strips. I wonder if the "oiled" filter WITH the glue strips was just too much, The glue strips did not allow flexibility in the filter so air flow was reduced somewhat. That combined with the "oil" caused a lot of issues maybe. But the "oiled" filter WITHOUT the glue strips perhaps allowed enough air flow so that the oil in the filter did not cause an issue. This is all speculation on my part of course but it is weird how if the oil was the problem, then why have most been able to run the oiled filters without the strips and not have any issues? Did the glue strips on the oiled filter caused the air to draw through more of the filter material, pulling out some oil that then coated the sensors? But once the glue strips were removed that allowed better air flow and less oil to be pulled out of the filter. Who knows!!??

It looks like if it was a restriction problem that it would get a code for that. I’m of the opinion that it is a tune issue since it corresponds with the new emissions regulations that came out in 2022. Some like myself are squeaking by and some are not. If I do a very limited amount of stop and go traffic in town, I have to take it out on the highway for a good spirited run to make it get to the timed regen. So far this strategy is working.
One way to find out would be to run all 3 filters on the same route, at the same speed and under the same load and check the MAF readings for each filter and compare them.
