6.7 Engine Air Filter Confusion

[OLEJOE]

That’s about par for the course. Get a remedy figured out that seems to work for some and they change the part to the crap people have been having problems with. I still think the problem or some of it is in the tune and programming.

Truth!
Definitely concerning. Makes me want to run out and buy up the ones I know work. I’m going to attempt a phone call directly to Fleetguard on Monday afternoon.

I’m more inclined to believe it’s a discrepancy with the MAF sensors. Hearing rumors……

I think whichever part or program in the tune that is reducing egt’s too much could possibly be part of it. My truck uses very little def so the temperature has to be lower at the DPF. I have to run my truck north of 75 mph to get any amount of passive regen and for more than 40 miles in rolling hills.
I know a Fleetguard Rep that frequents BITOG. I’ll PM him and see if he can find out any information on the change. I’ll let you know what I find out.

 

[mbarber84]

Mine is the same. I have to keep it 75mph on the highway to get consistent passive regeneration. So yes true tuning may be part of this too.

I can’t wait to hear what the rep has to say. Please keep me posted and thanks!

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. View attachment 65204View attachment 65205View attachment 65206

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. View attachment 65207

Looks exactly the same as that made in Mexico Wix that someone posted here somewhere a few weeks ago, which also just changed from what he would normally receive.

I’ve never had the Purolator in my hands but this one was posted for sale on eBay. Bears both the Purolator number and the number shown on this new Fleetguard substitute

Those glue strips look a lot thinner than the glue strips on the Mopars that I received a year ago. Regardless, I gave the two Mopars I had on the shelf to a friend with a 2018

I’ve got less than 1,000 miles on the odometer so have a while before the first filter change is due. I’m concerned that by the time I need a new filter I may not be able to find one that works correctly. Do I need to open the box now to verify the presence or absence of glue strips etc.?

What model year?

What model year?

2023

2023

The last 2023 I opened up had a Mopar 53034051AB in the air box. That is the same as the Fleetguard AF27684 prior to this new substitute issue. Both are orange foam and have NO glue strips on the bottom.

I sent him the pm. I’ll let you know as soon as I hear back from him.

I think my drive cycle change has done more to reduce regens than the filter change did. I have a gas burner I use if I’m not going very far. Less than 20 miles one way.

Really appreciate it! Hopefully this is just a temporary thing Fleetguard did to fill a void. I would be amazed if they outsourced this continuously

That’s what I hope is going on also. The 53034051ab filter I took out of my 22’ looked like it had been wetted or sprayed with something as the color was different in different places. I wish I could find an air cleaner housing from an 18’ to try to see if that would make any difference. The new ones still have the hole in the fender for the intake hose over the fender well. Mainly to see if the air being forced into the filter vs being sucked in creating a turbulence in the housing. The Ramair idea sounds good but I get tons of bugs that didn’t happen with the older design.

I heard back from him and he said he did not see where the 27684 had been superseded by anything. The other number he said he couldn’t find a cross reference to that number anywhere. He’s going to check into it further and let me know. I sent him pictures and explained our issues with the different filters. Should have more info soon.

That’s some good news. Thanks for keeping me updated. Hopefully there’s a solution to this. The other number was difficult to find. I couldn’t find a direct connection to it, but did eventually find that the Purolator filter has both the “P” number and their own internal part number on it.

As Jimmy stated the Fleetguard posted above looks identical to the Wix I previously ran. When I had the Wix I would regen every 100-200 miles. I swapped back to OEM and I drove 900 miles before it regenned again, happened yesterday actually. My DPF gauge never moved off 0 but I heard the engine change notes and when I scrolled to the regen screen I noticed it was doing a regen. I surely hope the filter posted above is a temp solution.

It could be tuning related but I ran the Wix with my CP tunes and there was no change in regen frequency. The only thing to make a difference was putting the OEM filter back in.

 

[mbarber84]

Update:

Called Fleetguard and spoke to technical support:
1. They have no record of that filter being changed
2. They do not show an updated part number
3. If they made any significant changes to the filter, they almost always update the part number to reflect the changes.

Called Geno’s and spoke with them:
1. They think it could be a case where Fleetguard subbed that filter out to another plant / manufacturer temporarily in order to get “caught up” on the significant backorder
2. They can not get any info from Fleetguard as to why the changes.
3. Mopar will not give them any info as to why the glue strips cause havoc with some trucks, but they have indeed inquired several times.

Isn’t this fun?…..makes me want to sell the truck and go back to my 1993 12 valve….ignorance was bliss!

I’ve only had 2 regens since I installed the FG filter in mine. 1 right after I put it in and the other 1 1003 miles later at the 24 hour mark. Now with 300 miles since the last one, it’s up to about 1/16 on the gauge. It had moved up to about 3/16 but I did about 30 miles driving 75+ and it dropped back to 1/16 and has stayed there for a while. This is the longest stretch I’ve seen other than the towing trips I’ve done. I don’t think the truck is having any problems, it’s all my drive cycle. But I do think if it was tuned just a hair differently to where the egt’s were a little higher, it would only regen every 24 hours. I’m trying some fuel from a different source and I’ll see how that does.
