Including the perceived problems with the design and which filters use it. I've tried the search function and all of the posts that I've seen assume that you understand the design.
Can someone explain the ecore design?

There's a good pdf w/a diagramme online.
I'm not the E-core expert, but I think some of the issues are from the nylon cage instead of steel. Other than that I don't know. I was excited when they came out (Ecore) and used them all the way up until BITOG. Then I started using the PureONE and am very pleased with it.

there is a nylon cage inside supporting the media instead of a steel tube. The idea behind this design is less waste and secondly better flow. The filter media is not supported by this cage as much as it would be by a metal tube with holes in it. Some believe the oil pressure can force the media through the cage.

Big holes + oil pressure = media coming through holes.
Look through the center hole of your filter and you can tell if its an ecore or not. You will see rectangular holes instead of little round holes
It varies which filter uses them but some that have used them or still do are STP, AC Delco, Carquest, Supertech.... there might be others and some might not be ecore but if you want to avoid ecore try these brands.

Mobil
Bosch
Purolator
K&N
Amsoil
There are other good filters but those are some top choices

Here is a PDF sheet on the Ecore filter:
http://www.servicechamp.com/prod_res_docs/Ecore Sales Sheet.pdf
Key differences from traditional filter construction are the nylon cage core and the dual-flow base with the combined anti-drainback valve (ADBV)/bypass valve.
I personally like the design, and like the concept. I think there is more room for improvement. I'd like to see some form of a metal mesh/screen placed between the nylon cage and media, to provide additional support for the media. It wouldn't have to be structural, but just enough to keep the media from pushing through the nylon cage. That seems to be the only real issue with this filter design (and it's already an extremely isolated failure anyway).

Here you go... read through this and you'll know everything you need to know about them:

I agree that a metal screen backing would solve my issues with the design and would put them back on my 'consider' list. Without it, no chance.

Making the most cost effective filter possible that will pass filtration tests. I couldnt see any other reason these filters were made than to save the corperation money and charge the same for the filter.

I appreciate the replies. Have a much better understanding of the design, but must confess that I lack the expertise to evaluate the merits/weaknesses. However, after looking at the pictures, I plan to avoidthem.

I always used a/c delco but i stopped the day i saw it changed to e core..
absolutely no e cores on my engines or the engines we build i dont like them at all

Good info. I am currently running a SuperTech w/ MMO. I am hoping at the end the filter holds up. I will open it and post it here after the result.
Having seen the failure pics of the e-cores, I'd avoid them too...
however, my 8yo Nissan has an OE filter that greatly resembles an ecore, but doesn't seem to have the probs.

filter has glued felt endcaps, plastic cage...but bypass and adbv are controlled in the engine block adaptor.

I love the nylon cage design. It flows very well, and by itself will not cause media to blow through. I believe that the combo ADBV/bypass used is the leading contributor to media failures in these filters. If it doesn't flow enough, the oil pressure will tear through the media.
The e-core filters that I have used on GM engines with in-block bypass valves have not had any issues with the media being blown through. I would have zero issues running an e-core filter on such an engine, provided that a silicone ADBV was not necessary to prevent valvetrain rattle on startup.

It very well could be the combo valve does contribute some to the problem, but IMO that plastic center cage is WAY too open which increases the risk of media blowouts. Also, that open center cage doesn't really help make the filter flow any better .... the filters with metal center cores with lots of holes don't impede any flow as the total area of all those holes is usually more than the center hole in the base.

They need to keep the media pleat spacing tight all around the filter.
from the ECore link
�� +10X more open area in core for improved flow
As Z06 stated--if you read it carefully, it does not increase flow--otherwise they would have stated x% improvement in flow. Unfortunately,I deal regularly with a corporation where you have to examine every word they say to extract the true meaning-this is a great example of marketing-

i stopped using them when they changed to e core and never went back
