Thread '6.7 Engine Air Filter Confusion'

Wondering if someone can shed some light on this issue. I’m being given conflicting information regarding the engine air filters for these trucks.

My dealer parts counter, as well as the service techs are telling me that engine air filter # 68517554AA is the correct engine filter for my 2022 3500 HO. I had them conduct a VIN specific parts search and send me a screen shot just to be sure. (See the attached picture) This information coincides with what we have listed in this forum as well as multiple other sources to include the folks at Mark Dodge, whom I spoke to over the phone.

Is the new filter better for the 2019-2014 trucks? Is the oiled AB not ideal for the 2025-up? If it's better for those trucks...I'm going to say it's also better for my 2014, right?

Or just a supplier change, again?

(Currently using 53034051AB in my 2014.)

EDIT: We're behind. It's already a few posts deep over on Grumpy's forum.

It’s listed as being a superseding part number for 19 to present trucks. Sounds like grabbing at straws to try and solve the Regen problems some are having and as you mentioned possibly a vendor change. I just thought it was interesting with all of the information on which air filter to use.
 
Guess I was smart by only buying & using the Fleetguard AF27684 air filter, its never been oiled thus I would think it would be safe to use in the 2025 & 2026 trucks...

I’ve only used that filter also. But is it because it is contaminating the MAF sensor or is it because it’s more restrictive ? If it’s restriction, that minuscule amount of restriction should be of no importance. Why is the 0531AA filter ok for use in any year up until 19 ? Bad tuning and grasping at straws.

AF27684 is same as 53034051AB. So if the latter is oiled, former is also.
 
What’s different before 2019 ? The intake tract before the air filter.

They don't want the older trucks using the better filter because they aren't as sensitive to the restriction and it overloads the supply chain. Or perhaps the 2019+ filter actually isn't as good of a filter but those trucks need the lower restriction to be happy.

It's all internet speculation (see 29 page megathread) but my 2014 was happy on a purolator and now it's happy on a 53034051AB.

Your 2014 would be happy if you stuck a sock on it. (though I wouldn't recommend that as a good filter).
 
I have the new # filter on order and I will let everyone know if it helps my soot loading issue since my last air filter change.
I think I may have received a defective 53034051AB, because after the change my regens went to from the timed 24hr, to soot load regens at 10-15 hrs.

Makes me start to wonder.

My truck, which has never ever given me regen issues before, started after an oil, fuel, and air filter change in the spring. I didn't ask for the air filter change either. My son works at the dealership and thought he was doing me a favor. That said, I did have a bad PM sensor that was throwing sensor codes and excess regen codes and has since been replaced. Too early to tell if the regens have changed as I don't drive it much off season.
 
I have used a Wix air filter for years and never had a problem ,

That’s what is weird about it. Some have problems and some don’t. It would be really nice if someone could check out the differences between problematic trucks against one that has zero problems. But we might get somewhere then.
 
The new replacement filter has glue strips from the pics I’ve been able to find. Haven’t had a chance to fondle one yet.

That’s what my truck was doing until I changed to the FleetGuard filter when the truck was new. I changed to the FG filter @ 6278 miles and now with 32828 miles, it has had mostly 24 hr timed regens since. I occasionally get a short soot based regen that I can’t explain but most are at 24 hrs with nothing showing on the EVIC DPF gauge.

Yes, it does. My son was able to swap a Mopar bagged AB filter for the new one before he left my RAM dealership <sad face for me> for his new job with the county he's in <happy for him>.

Unfortunately, the other AB filter I had from Genos wasn't in a Mopar bag so he couldn't swap that one.

I have 2 new AB filters that I got from Geno’s but they look different from the one I took out of my truck the first time. It was more yellow than the new ones and it appeared to be heavily oiled but the new ones I have look more like the FG filter.
Let us know how the new filter is working.

Haven't swapped it in and don't really intend to any time soon. Filter was just changed along with a MAF (both without my knowledge and consent), but as part of a service visit for PM sensor errors. Dealer (partly the diesel tech, partly my son involved argghh) did not do a MAF relearn like they're supposed to and I ended up having to do that myself. I get it though, dealership is not in a location that's conducive to the stupid relearn requirement to run 3 cycles of 2600 RPM for 10 minutes, with 10 minutes of key off between each one - that RAM should have a damn quick learn available for.

I'm not driving the truck around town if at all possible now until I know how it does on regens once I start towing again this spring/summer. I've still got a Maxcare and CARB state warranty so not too concerned if it still has issues and they need to replace the DPF or something else expensive (isn't it all?) is schwacked. Might do an ATV daytrip with a friend next week so it will need to get used, but that's light towing 2 ATV's (like it will even notice haha) and highway for a good chunk.
