6.7 Engine Air Filter Confusion

They don’t get the best reviews, the consensus is to run OEM.

I couldn’t get OEM and turned to Doc’s. I’ve not encountered any of the problems that others have. I buy other things, like windshield wipers, because the quality of the aftermarket is so sketchy at times.

FleetGuard doesn’t make a fuel filter that goes in the rear under the bed. Im using a Baldwin pf46152 for the rear and FG fs53000 in the front filter. The air filter is AF27684 and LF16035 for the oil filter.
Check out Geno’s Garage. They have genuine Mopar and FleetGuard products that are not knockoff Chinese clones. Great people and products.

After I replied I thought I remembered you were in Australia. Sorry for the confusion.

How often is everyone changing their air filter ? I thought about putting a filter minder on my truck but still haven’t. I changed the factory air filter at 6278 miles but it was solid black even with that few miles. The air filter in my truck now has 11,700 miles on it and looks considerably better than the factory one did. I also put a FleetGuard AF27684 filter in when I changed it last time. Just curious what kind of mileage people are getting out of them.
 
The truck will tell you when it’s restricted, so no need for a filter minder (which is why they are not used anymore).

I’ve been doing once a year changes, even thou they are good for 2 years per the manual. (Or up to 30K miles).

What? Does it throw a code or CEL ?
 
I have 16,300 miles on my 21 since September 21. I change air filter, oil, oil filter, fuel filters and cab filter every time and have done so 3 times now. First time was after 6,200 miles.
On all 3 air filter changes they were dirty but not terrible but that was with very little city driving and 80 percent towing on mostly highways.

I changed mine in September of 23. I live in a rural area but 99.5 % paved roads. Limited in town driving but horrendous amounts of pollen during the spring. Got a sand storm in New Mexico earlier this year but we sat it out. Probably still had a good bit of dust on the roads and in the air that wasn’t visible while driving. My last UOA showed acceptable levels of silicon in the oil.

I haven’t seen the message on a gen 4.5, but on the older 6.7’s the EVIC flashed a message saying to service the air filter or something along those lines.

I was really wondering about the change interval because of how picky these trucks are about the air filter. I guess if the truck starts regening more often, it probably wouldn’t hurt to change that first. Thanks for the info.

Yearly check and replace if needed. On 3rd filter. Changed factory at 14k to Mopar 53034051AB then Fleetguard AF27684 at 25k. Haven't notice any differences in regen aside from shorter intervals overall.
 
My 12 says ‘’ service air filter’’ er somethin like that. I’m sure my 19 does also. But with Stellantis the message now a days might be in French or German perhaps. :oops:
 
I’m only on my 2nd air filter and have 26k miles. Mostly paved roads. In theory dirtier they get, the better they filter.

They do filter better with some restriction but with how picky they are about which filter to use, I was afraid it might start making the truck have issues without giving any indication of what was wrong. I might run mine until the next OCI and change it at that time.

Yea I’ve been running a “AA” for the last 14k, no issue. How they got the 19s right but not the 22+ is strange. Hopefully something is coming down the pike for you guys soon!
 
Well, I made it through this mega-thread! I have 2022 2500 Big Horn used for my business. It constantly threw error codes with the factory air filter. The codes started at 2K miles. They changed the Mopar filter for another one at no cost. I put a WIX filter in it 5 months (and 7K miles) ago. It still kept putting up "frequent regen" codes. I brought it to the dealer mistakenly thinking it would be under warranty (bought the truck as a leftover in the summer of '23 and it only has 20K miles on it). According to the tech, I am "idling" too much causing soot buildup. My business often works in NYC and surrounding cities in NJ. As you can imagine, there is constant stop and go traffic. We never let the truck sit and idle at jobsites... hell, I have instructed my employees to not even use the remote start!

Dealer claims the recent issues were due to the WIX filter... even after I reminded them it happened with the first two Mopar filters. They charged me $500 to do a "soot cleaning." Am I an idiot (don't answer that!!) for thinking a $90K truck shouldn't need a soot cleaning at 20K miles? I have 2 Duramax trucks and this crap doesn't happen to them.

Even if you are deleted use the orange filter. I had the black one in for a short period it was idling slightly rougher than normal and would have smoke when hard on the pedal. When I reinstalled the DPF it was getting to 1/2 on the gauge and reneging every 200k km. I knew it was the filter but my dealers were out of stock so once they got some in I swapped out the filter and after the system regened the last time it has been 1000km and 0 dpf filter soot load on the gauge.

"Frequent regen" on a 2022 has a TSB to replace the DPF. See the Frequent Regen thread.

As to the air filters, Mopar 53034051AB or Fleetguard AF27684. Nothing else.

My 2020 has an egregiously high number of idle hours comparatively and I don't have any of these issues.
