If GM has customers skeptical around their AC Delco filters, they have no one to blame but themselves. The ecore business, particularly at the outset, left a bad taste in a lot of people's mouths. It's a much different situation than when I was buying AC Delco specifically because of good construction and a cost significantly less than any of the competition on the shelves here. Motorcraft has people, at least here, wary of QC, too, thanks to Purolator.
Certainly, some aftermarket filter manufacturers have been very careful about ensuring good match to what the OEM intends. Wix has been a good historical example of that, noting how they handled various Chev filters over the years, not to mention separating model numbers where some filter manufacturers did not, notably when they hived off two part numbers for Honda and Nissan/Infiniti applications.
