Hmm. That's not a problem.

Then maybe they'll advance ducted injectors and we won't have all this EGR DPF BS at all.

All,
It looks like the Fleetguard AF27684 shipped from Amazon has a new sticker or part number covering the old part no. Not sure if they changed part numbers or if this is an Amazon-only thing, but this filter dropped right into my truck and appears to in fact be the 27684 filter.
Here's the original filter with just over 20k miles. My truck has 0 regen issues and DPG guage is rarely off the 0% mark. As info.

Looks better than mine. It has 53k miles on it but with all this air filter hoopla, (did I get the correct filter or not?) I plan to keep running it as long as it's in good condition, I'm not losing fuel economy and I'm still regenning at 24 hour intervals. I check it every oil change, and clean it to the extent possible.

That’s what the box looked like my Fleetguard filter came in. My used filter looked like yours also but it only had 6300 miles and 167 hours on it. I don’t know why or if it was just coincidence because of the mileage but my truck runs completely different from how it did before. It’s more responsive and the idle doesn’t vary like it did before. Before I changed the filter, it would idle 50-75 rpm higher at times, and I thought it might be because the a/c was on, but it doesn’t do that now. Nice and smooth. It’ll be a little while before I can tell if it is going to affect my regen frequency but it has only done 1 so far and it was right after it was installed. It has been 610 miles and 14 hours since the last regen but the first 400 miles was towing and the DPF gauge is still on 0.
I finally got my 2nd regen @ 1003 miles and 24 hours after the last one and the DPF gauge was and still is on zero.

Interesting..
I haven't run my truck yet with the new filter, but if there is a significant change in how it idles or runs ill report back.
That said, im lucky in that I haven't had any regen issues to this point but with how sensitive these trucks appear to be regarding the air filter they are breathing through, I figured id better change mine out.
Just figured I’d post this here for reference. I was cleaning out my shop today and found the original NAPA Gold 6930 air filter that I had used on my 2022 HO. I removed it when I did my second oil change and set it aside as a backup in case I suffered a filter failure and needed to get by in a pinch. It’s interesting to note that this was the first filter I installed in my truck back in May of 2022 when I completed its first oil change. I’ve since attempted to buy the same 6930 from NAPA, however the design of that filter has changed at least twice since May of 22. The current version looks nothing like the original. You’ll see below I have it sitting next to the Fleetguard AF27684 I just recently removed from my truck after doing a fluid and filter service. NAPA FIL6930 on the left, Fleetguard AF27684(In the second picture below, the 6930 looks taller than the 27684 but that’s only because the filter itself was “bowed” and not sitting flush 
I'll add a data point. I've got a 2019 3500 HO, with the fuel pump recall completed. This is a work truck and not a daily driver for me. I tow with it about 50% of the time, and the rest of the time its pretty loaded for work. I rarely have an active regen and pretty much never have an active regen while towing, passive does the job. I've watched the truck on long trips to see if it does an active regen every 24 hours. It does not so long as passive keeps up, I had a trip where it did an active I believe at 32 hours.... Anyway, I've been using WIX filters from amazon 46930. I did notice that the last filter was orange around the seal and the new one I put in was black. We'll see if I can detect any increase in active regen's, Going on a 700 mile tow next week, then doing work. I only get active regens when doing a series short trips at low speeds below say 65mph, and the engine is mostly cold.
Interesting. Just curious what you base this on. I've been under the impression they trigger the regen at 24 hours regardless of any other factors.
My truck only shows the active regen in progress message on the dash if I trigger a manual regen, which I've only done once and will not do again unless it's absolutely necessary. During any other regens, the dash doesn't show the active regen in progress message, just the 0% gauge. Point is, it's just challenging to keep up with regen status, on my truck anyway.
I did a thread on this, where I drove on a business trip from Houston TX, to Indianapolis and back, and watched the regen display the whole way and never saw an active regen at 24 hours. (will have to find it). I had a regen about ~32 hours into the trip as the DPF finally reached 50% to trigger an active regen. The every 24 hours for an active regen may not apply to all diesel configurations. Mine is a 19 HO with the fuel pump replacement and reflash. Mine does show an active regen in progress when it occurs. I use my truck mainly for long drives and towing so the passive regens are generally sufficient for me. I also have 48 cetane fuel in the Houston area which combusts more easily thus generating less soot than the standard 40. I also have a 50+ gallon tank and often go 800 miles between file ups. I have not had a problem with frequent regens in this truck. There seem to be a variety of reasons that some people have very frequent regens. Some of it is driving habits, some is possible sensor problems, some maybe programming, fuel, etc. I find if I'm towing or driving at or above 80-85 then there is enough load for passive regens to keep the dpf clear.

The simple answer is that you’re missing it occur. All 13+ Ram/Cummins diesels, that have DPF’s installed, have a 24 hour regen. You could be towing at GCWR up a grade 100% if the time and it will still happen every 24 hours.
It’s easy to miss, even when you’re watching for it. My dad saw his first one ever on Saturday, because I pointed it out. Thats with a CTS3 that has the led during regen. He’s had a truck that regens for 5+ years.
If you when your last regen was then you can watch for the next one, but it’s not exact on the hour meter. I’ve seen it happen anywhere from 23-25 hours on the hour meter based on they indicate.
The regen % PID is the easiest way to determine when the next one will occur, either by time or soot.
Ever thought about getting a CTS3 to monitor it?
@AH64ID spot-on.
Although I do wonder if, for some weird reason, some trucks (either randomly or by certain year) may not contain the (programming?) to provide the message to the operator.
I’ll give you an example I am 100% aware of. If you buy a 2023 truck with the fully digital dashboard, that truck will not tell you when a regularly scheduled active regeneration is taking place. I’ve had several people pay attention to this and the message is not there. However, they WILL give you an intervention message with the “continue driving” portion if you’re not allowing the cycles to finish, or not driving in a manner conducive to regeneration. Conversely, the non-digital dash trucks still have both messages.
So somewhere in the software, programming, etc….there’s something either deactivated, not functioning properly, or completely omitted that does not provide the truck will the ability to send the normal regen message to the dash. You can see the soot load falling on the gauge, but you don’t get the message.

The joys of programming. @Blythkd1 has a C&C so there is that variable too.
That’s where the CTS3 is handy.
It has crossed my mind but probably won't happen. I just started a full time job at home again so terminated my hauling lease. I'm casually watching for a new gas truck. No hurry but it'll probably turn into a gas truck again someday.

I totally get it, did the same thing 2 weeks ago
I had already gone back to a gas truck after a diesel (GM) debacle back in 2021. Then I got back into more hauling so I ordered the Cummins truck. It's been ok but I don't know how long it'll be ok. The '22 Cummins failures have me made a bit nervous. And of course, I have no confidence in the emissions equipment lasting long term. I'll just be more confident in a gas truck and it'll serve my current needs just fine now. I may never own another modern diesel. It's a shame what the govt and HP wars have done to their longevity.
I hear you on that. I like diesels for many reasons and have owned many. But between poor manufacturer engineering choices; stares at high pressure EGR (EGR connected pre-dpf), using post injection events to do an active regen (instead of putting an injector in the exhaust), and CP4 fuel pumps.... Some manufacturers place the EGR intake post DPF and eliminated intake soot build up (mostly) and put an injector in the exhaust for regens eliminating oil dilution problems.... But at least RAM stopped using the CP4 unlike some others....
Now the whole unusual sensitivity to air filter choices, really RAM did you think that one through... But at least people will figure this out and know to use the correct filter instead of discovering it later....
The main reasons in my mind to buy diesel are, you need it for your towing situation, can make money with it, or just love diesel engines. For most people gas is a better choice as a daily driver / personal use from a $$$ perspective. I think all modern diesels in HD trucks are going to be problematic from a reliability perspective for a range of reasons, why ford do you still use the CP4.... But from what I've learned I'd say that Cummins at the moment has the best potential for a long life, with minimal money $$$ thats why its my company truck. But I don't expect as many trouble free miles from my 2019 Cummins as I have gotten from my 7.3 power stroke. Which has no power.. But I like driving my newer truck a lot better than my 2000 Ford F-450.

The Ford 6.7L is built around the CP4. No other pump will fit. However, S&S with PurePower recently released a replacement pump that will fit for $2,000.00. I considered going that route with my F350 DRW but other issues caused by the dealerships caused me to switch brands entirely. The CP3 is the primary reason I went with Ram.
Well….here’s a new plot twist to add to this:
Buyer Beware.
I’m getting reports from several owners in one of the Facebook truck groups that there’s been a change in filters on the Fleetguard AF27684. Or at least those coming from Geno’s Garage.
As of today, two people received their orders from Geno’s expecting the orange and yellowish Fleetguard AF27684. The box and packaging say Fleetguard, correct part number, but what comes out of the box is not the same as what we’ve known to expect. Also, Geno’s own website now includes a different picture for the Fleetguard. New filter has part number P33478, is made in Mexico not USA, has black foam, yellow media, and now includes two strips of glue across the pleats. It is unclear at this time why there’s been a switch. I tried to find that part number and cannot come up with anything definitive. The closest I could find is a P33478 / A56314 manufactured by Purolator.
Not sure what’s going on but I’m going to do some more digging. Will report back. In the meantime, if anyone else receives this filter in place of the AF27684, see what you can find out. Curious if it will cause any issues. I’m reluctant to try any new air filters due to the hassle the wrong one caused me last time. I finally have this truck on track to get back to normal and can’t afford another upset on substandard parts.
This is the Purolator filter I found after searching the web. This one is for sale on eBay. Carries both the Purolator number and the new (Fleetguard ?) number.
