Like this? Green line is where they are "bonded/pressed"?There is only one overlap, not two.

The Fram I use on the truck is a spin-on and has a metal crimp and wire backing. It's a very well constructed filter.Okay, if this is for a Pentastar engine, this would mean it's a cartridge filter vs a spin on filter where the problem is being reported (correct?). This problem hasn't been found yet on the spin on versions yet.
No, the cartridge filter that is the subject of this thread is in the Durango 3.6L Pentastar. I was just stating that the spin-on Fram I use on the truck, which is a Chevy 6.6L diesel, is a well constructed filter.So then it's an aftermarket modification to use a spin on filter for a Pentastar engine?
If they used a good metal crimp on that same 3 layers of folded media setup instead of trying to press "bond" them together without any glue, it would be way more robust seam. It's probably a cost cutting move in the manufacturing process that seems (or is it "seams", lol) to be back firing.If the crimp holds, we don't care that there are holes all the way through, because the oil can't get to the inside of the filter. If the weak end of the crimp pulls apart, the crimp holes allow oil to flow through the paper unfiltered.
That is exactly the kind of test that needs to be done to see if this really is a problem or not. It may be that that particular one pleet that has the joint is actually completely closed together, and that it's easy to pull apart when you cut the filter open on the ends. If that is the case then a particle capture flow test would show that the filter still performs to specifications.Bet those filters wouldn’t have done 99%@20u on Ascent’s test bench…![]()
Please see the above posts from the OP - he didn’t simply pull this out and spread it as you suggest.That is exactly the kind of test that needs to be done to see if this really is a problem or not.

If that is the case then a particle capture flow test would show that the filter still performs to specifications.
Also, it would be interesting to see what that particular joining pleet looks like by carefully cutting the ends off of the filter section without expanding the radius, and not opening up the media to be flat, for that section of the filter. In other words, without physically changing the spread of those cleats at all around that area. One could cut the filter section from top to bottom instead of cutting the ends off, and leave something like 25% of an arc of both ends for the filter still glued to the media on the top and bottom so that the arc that section is at Remains the same as it is in real use. Then examine that particular area with light and magnifying. In other words we need to take more of a real life look at those pleets without actually physically spreading anything apart in that area to get an idea of what's really going on.
Oh man, I literally just put a Fram Ultra 7317 on my CR-V and threw away the box. No idea where it was made. I might pull it and cut it open.
I do have a Fram Titanium which was made in the US. Anyone seen issues with US made ones?
I also checked a US-made cartridge style Toyota Fram Ultra and couldn’t tell if it had any issues as the pleats were too tight. It did not look problematic since the seam was very tightly packed in.
I’m not sure what to use at this point. People say Wix quality is dropping and the XP is a rock catcher. I just cut open a regular Wix that looked great though.
Some people don’t like Purolator because of some past issues with torn anti drain back valves and off-kilter alignment, but these seem isolated to me. Some think the Boss has an inefficient particle filter capability but the recent testing I’ve seen shows it’s better than other M+H filters.
Supertech filters seem to offer great value and surprisingly high quality. I am just not sure about their ability to filter 20 mu particles.
My research and experience has led me to conclude that I would run:
Heard in things about Ecogard but have no direct experience.
- Purolator Boss
- Wix regular
- Mobil1
- Supertech
- Fram Endurance
I’ll report back after cutting open the Ultra I just installed.
How does the bonding process work? I took pictures of the 4 Fram offerings this morning. The EG, TG and Ultra appear to use the same technology. They also get marked with a blue dot at the seam; EG and TG on the bottom half, Ultra on the top half. The purpose of the dot may be for:^^^ Makes sense now. So it's actually 3 layers of media "pressed/bonded" together before one layer separates from the other two.
Nah. Topic filter is a cartridge application made in Brazil. Otoh, XG7317 a spin type made in the US. Worst seen on them (post use) since the change in media, is some wavy pleating. Run it the full oci.Oh man, I literally just put a Fram Ultra 7317 on my CR-V and threw away the box. No idea where it was made. I might pull it and cut it open..........
Clearly you weren't around when the Motorcraft and Purolator filters were tearing in service.Bottom line. IMO our best bet is to use a OEM or OEM made filter for your best results. OEM manufacturers randomly test every every part they buy and stand behind the result.
The Fram Endurance doesn't have the same marks on the seam as the other 3 filters shown. The "squares" you see in the Endurance seam is the wire backing, not marks from the machine that had "bonded" the seam like on the other 3 filters.How does the bonding process work?

They also get marked with a blue dot at the seam; EG and TG on the bottom half, Ultra on the top half. The purpose of the dot may be for:
1. detection that the seam bonding process is complete?
2. to orient to the seam quickly for inspection?
The Endurance does not get the blue mark. The joining process looks different or perhaps the mesh is making it look different?
