Well, I'll give you the chronology in terms of ebb and flow here.
Old style "clicker" Champ filters. Worked just fine, but showed the highest incident of fatigue related issues (breached media at the sealing seam) in services of unknown length in at least one quick lube situation.
Ecore introduction: Some initial bonding issues with the fabric/fiber/whatever end caps. Not truly an issue ..but something to nitpick. The combo ADBV/bypass kinda squished everything together anyway ..but nitpick's pick
I don't recall ever seeing a BITOG user have an issue with the clickers outside of the quick lube owner (under the Warner label) and he would never bother to qualify how long the filters had been in service. The Warner's that were used on GM vehicles didn't have the issue ..so this pointed to the clicker bypass as being the longer term problem as the media saturated.
The clicker has been abandoned in the ST line in favor of the "blue button" and outside of one user putting an Ecore ST filter on a high performance Chevy big block with the in block bypass defeated/plugged, I can't recall an issue with them.
I used to buy them every time I went to Wally's. When they were $2.02 ..it was hard to resist. Now that they're so much closer to MC ..(I miss the BOGO AATG though)
