This is a cut and post of a new AC Delco PF1250 (25014520). Date code: 13297ES 11:29 Product of USA Birthday: Oct 24, 2013 11:29 AM Maybe someone from the community can confirm the date code format and the factory. The as built condition of the filter is relatively good with a couple of minor points I will address. IMG_0504-ACDelco PF1250-13297ES-Exterior Label I have run perhaps hundreds of ACDelco filters over the years. This one has a good looking blue paint scheme and an easily read label. IMG_0514-ACDelco PF1250-13297ES-Date Code 13297ES 11:29 Product of USA = Oct 24, 2013 11:29 AM Maybe someone can correct and identify the factory too. I ordered 3 each of these online and received two recent ones and one old one. Rather than send it back, I wanted to see what possible improvements have been made. These look like Champion Labs made filters. IMG_0515-ACDelco PF1250-13297ES-Base end This base end shot clearly shows the auxiliary base plate that supposedly assists with blind installation. It also modifies the oil flow for inlet and bypass functions. IMG_0516-ACDelco PF1250-13297ES-Base end #2 The angled view shows both inlet holes and some of the smaller bypass holes. The cage can be observed through the thread end outlet hole. You can identify whether the core is an old or new design. This shot could have been better. IMG_0517-ACDelco PF1250-13297ES-Filter 0 degrees The narrow pleat is the splice but Champ Labs orients the splice toward the core. So, it is a bit hard to find. None of the pleats were wider than 0.375" wide and I do not believe it would present a problem during use. IMG_0518-ACDelco PF1250-13297ES-Filter 90 degrees While not as even as I have seen, there are no issues here. Note, the leaf spring sits tightly against the dome end of the filter and centers the filter assembly very well. It is a snug fit so I do not believe it will leak. IMG_0519-ACDelco PF1250-13297ES-Filter 180 degrees There is the second 0.375" wide pleat and I do not believe it will present a problem in use. IMG_0520-ACDelco PF1250-13297ES-Filter 270 degrees Last shot of the media. The nubs on the thread end fiber cap seem to center the filter assembly at the threaded end very well. IMG_0521-ACDelco PF1250-13297ES-Filter dome end Dome end view of the filter on the combo valve sitting on the base plate. You can clearly see this is the old design core with only 4 vertical bars. IMG_0522-ACDelco PF1250-13297ES-Filter dome end #2 Angled shot of the dome end of the filter assembly. This is the wide window that everyone gets excited about. I would prefer the new core instead of this one. IMG_0523-ACDelco PF1250-13297ES-Filter base end The circle supports are on 0.5" centers and the window is over 1" wide. IMG_0524-ACDelco PF1250-13297ES-Filter thread end with combo valve The interior lip of the nitrile combo valve serves as the pressure relief valve. IMG_0527-ACDelco PF1250-13297ES-Filter thread end with combo valve #2 This shot confirms from the centering of the bite marks from the inlet holes the filter was adequately centered. IMG_0528-ACDelco PF1250-13297ES-Base inside view The inlet holes and the pressure relief holes were sufficiently deburred in my opinion. There also seems to be sufficient clearance so the combo valve can serve as a thread end gasket. IMG_0529-ACDelco PF1250-13297ES-Base inside view with combo valve This shot gives an idea of how wide the gasket seal is. The lip is well within the ID of the core. IMG_0530-ACDelco PF1250-13297ES-Filter thread end cover removed Only 2 pleats were about 0.375" wide and not likely to be an issue. However, when I pulled the cover off this one, it peeled off very easily. The only real way to say if this is good or bad is just to run the filter. The age of the filter might have been a factor also. IMG_0531-ACDelco PF1250-13297ES-Old cage design This is the old cage design with only 4 vertical supports. IMG_0532-ACDelco PF1250-13297ES-Old cage design #2 There are also 5 rings on 0.5" centers. IMG_0534-ACDelco PF1250-13297ES-Cage on base showing bypass holes The bypass holes are well within the ID of the cage. IMG_0537-ACDelco PF1250-13297ES-Cage on combo valve This shot has the combo valve in place so you can see the location of the pressure relief valve. Internal measurements: Filter assembly height: 2.25" Paper width: 2.125" Number of pleats: 56 2X pleat depth: 1.5" Media area: 178.5 sq in. Filter OD: 3.25" Core OD: 1.75" 2 pleats were up to 0.375" wide 1 pleat was up to 0.25" wide Thread end cap peeled off very easily Cage height: 2.0625" 4 vertical supports 90 degrees apart 5 circles on 0.5" centers In summary this is a fairly well manufactured filter but does have the old cage design. The base end fiber cap peeled off very easily and this may or may not create a problem in use. The end caps of the Champ Labs PH820 that I cut and posted earlier were very tightly glued and I tore the fiber end cap getting it off on that cut and post. There were two 0.375" wide pleats which I don't believe would cause a problem either. I prefer to use one with the new cage design and a bit better glue job. I really do not have the necessary equipment to evaluate the media but this media looks pretty good and potentially thicker than the Champ Labs PH820. If I had old ones in the stash, I would not pitch them, I would check them out and use them up if they don't cause issues. There is one thing missing in these photos. There is absolutely no RUST!!! This was a problem for the Motorcraft FL-820S. In about 2 months, I will have 5000 miles on one with the new cage design to do a used filter cut and post. Additionally stay tuned for a new cut and post of one with the new cage design. I think all the eCore lovers will like that one better. The one that wins the beauty contest so far is the WIX 51372. Until then, enjoy the post.

Ehhhh I'm not a fan of ecore filters but I have used many of them only had one where the endcap was separated but in all likelihood was still functional

WellOiled - Nice write-up. Not a fan of eCores either, but they do seem to have been getting better over the last few years.

I would be happier if they had the following: 1. Silicone ADBV 2. A better glue job 3. A real bypass valve with a spring and seat 4. More media with maybe a bit more efficiency I think the new core is much better and lowers the risk of a media blow out. Some folks with Grand Marquis might like it because it is smaller to get into that tight spot.

ZeeOSix - The next one up is a new one with the better core. They tightened up the window. Maybe not enough for the filter connoisseur. It has better pleat spacing and the glue job is better. So far I have not had any startup rattle. I would almost assume that if startup rattle occurs, the bypass function is also compromised.

crazyoildude - Since Mann-Hummel also owns WIX, I hope they do not somehow ruin WIX. I bought a Fram PH2 and TG2 to put in the filter contest so I may do those next just so we have a few more non-eCore / non-Mann-Hummel filters. The Fram Ultra seems well covered.
