This is what I see on the dash in between regens. At the end there was passive regens while towing. The same between each regen at 8000 miles now.

6.7 Engine Air Filter Confusion

Yeah. Starting to think the same. I don’t think it rose and fell like that before but it might not be solely related to the filter change.

Has anyone checked the intake ducting in front of the filter box? I noticed mine is kinda kinked with the top part in the curved section kind of dipping down. I don’t know if that could be an issue or not. I know the S&B CAI’s have a different routing for the pre filter piping. I ran the AB filter in my 18’ for 25K miles and changed to the AA filter afterwards. In less than 8K miles the AA filter had the same restriction as the AB had with 25 K on it. Just thinking out loud.
I called Ram customer service back in early April 2023 to inquire when they planned to initiate the recall campaign to install the missing Particulate matter sensors.
I was told “expect to see a recall notice by mid May”…….
The 2022 cab and chassis recall has been active since December 2022. Not sure why there’s a hold up for the pickups. The 2023 trucks are all being shipped with that sensor in place.
It’s worth noting that sensor has absolutely nothing to do with regenerations though.

Lots of talk on here regarding wrong filters being associated with higher frequency regens. I changed my oil and fuel filters about 4k miles ago, and this week my truck has regenerated twice and the gauge is showing it fill up already. My existing filter is correct, and I have filters on hand. How often are you guys changing them? I have just under 15k on the truck now. Wondering if my filter is clogged enough to kick the extra regens in place…
I change my engine air filters at every oil change. That usually falls between 10-15k miles depending on the type of work I do with the truck within a given interval. The air filters are relatively inexpensive and a key to efficient operation with these trucks so I feel like it’s a small amount of money well spent. The last few times I’ve pulled the filter out, there was a fair amount of fine road debris, insects, dust, leaves, etc in there that I thought it best to change it. I’m at approximately 11k miles on my current service interval and I’ve noticed my truck seems to build soot a little more quickly than when the filter was newly inserted. Passive regeneration doesn’t seem to be happening as efficiently either. My suspicion is that the air filter is getting dirty again and may need changed. There’s a noticeable difference between when the air filter is brand new, and when it has accumulated mileage.

Interesting. The manual says to “inspect” every 15k but not to go past 30k. I inspected it, but this is the first diesel I’ve owned and maintained. I was looking at it like I did my gas trucks, and for them it would have been fine.
Anyone else go longer or shorter than that on average? Maybe I need another thread as to not highjack this one….

What I would like to know is “What did they change on this generation of trucks that makes them so sensitive to the type and condition of the air filter?”
As would I. But there is definitely something different.

The complete air intake system is different from the 18’ model I had. They are now (since 19’) using the same type intake system as the Hemi with the fresh air scoop mounted on top of the radiator. Where the intake tube comes out of this it turns 90 degrees and the corrugated plastic tube does not make a smooth turn with the top of mine dipping down into the airway. I’m wondering if this part of the system is causing some kind of restriction and if it’s not actually the filter causing the problem. I’ll try to get some pics of mine but it’s hard to tell if it is actually blocking the airway or flow.
I’m wondering if a second air inlet coming from the fender like the previous ones (18) did would alleviate some of the problem.

So my DPF gauge krept up above 40% on my way home, after just completing a regen yesterday morning. I changed the air filter once I got home. Here’s pics of my filter on the bottom, and the new one on the top. This is after 14,650 miles.
I was hoping between changing that and taking a camping trip pulling a 12k trailer that it would work itself out, but while pulling the camper home to load it the truck went into regen again. I didn’t keep track since yesterday, but it’s probably 2-3 hours and 60 miles between them total.
In my gas truck I would have changed this filter too, but it didn’t look this bad 4k ago. If this corrects things I may be in the “change-it-with-the-oil” camp too.

It looks like it definitely needed changing. When it gets dark like yours on the clean side it’s done. Must be some really fine dust where you are. What oil are you running in your truck? I’m not having any issues yet but I only have 5K miles and 3K of that was towing.

It was changed at the dealer at 5k and I don’t know what they put in. It was free so I took it to clean out the engine. At 10k I put Valvoline blue in it and sent a sample off to blackstone. Everything came back normal for what the dealer put in. So I’ve got almost 5k on the blue.

Thanks. I was just curious. I changed mine at 2300 and put RotellaT6 5-40. Going to change it again at 7500.

I didn’t mention I put 10-30 in mine. I’m in Denver and we pretty well never go below 0 so I think it will be good. With my luck this next winter will be nothing but and I’ll have to change it. I couldn’t find t6 near me to save my life, and grabbed blue on Amazon. Then a month or so back Napa had a deal on blue and I stoked up a few changes.
Seems to be three main schools of thought on oil: blue, T6, and amsoil. I can never trust people touching my trucks so that takes me out of the dealer group completely.

I agree with you on that. I do all my own maintenance but getting older I may take mine to have the tires rotated. I do the rest of it.

I wonder if the intake location picks up more crap for the the filter to filter out. It also gets a better flow of air, so maybe it’s a tradeoff.
I changed my initial oil at 1,565 miles and will change it again at the 12 month mark on the fuel filters. That will put me around 11K miles on the oil. The air filter will also get changed. I plan to do fuel filters, air filter, and oil/filter at the same time annually.
I rarely see temps below 0°F (it’s had been over 5 years since I’d seen it), but this last winter I saw -5°F in November and -18°F, -13°F, and -16°F in January. I’m glad I opted for 5W-40, for both cold weather and hot weather performance. With the lack of a real oil pressure gauge you won’t know if it’s too cold for your oil right away.

We never see -0 temps but we regularly have high 90’s-100’s and very high humidity. Dealer said use 5-40 and glad they did as that’s what I wanted to use. Maybe they will get the air filter thing figured out.
Where were you last winter? Or the one before?
I've been here since 1992 and we sure do get below zero. Dec 2022 set a record low -24.
I'd say we get between a couple 2-3 and 5-6 below zero days almost every winter. It's certainly not sustained, but they exist.
FWIW, I run T6 5w-40 since I only change every 12 months.
I think if these current weather patterns hold, this winter isn't likely to be extremely cold, but it will bring extremely heavy snowfall.
