AC Delco E-core filter durability/reliability ???

get the comparable filter for a few bucks cheaper. STP 10060, or if you can find on rock auto, The Luberfiner equivalent 48. All 3 are ecores, and all 3 are nearly identical.
other than. The ecore options,the fram family of 10060s, Bosch Family of 3334, and purolator families of 12222 are all same size.

The STP is comparable, but I am sure that the media is different than an ACDelco. The reason is because my local AutoZone stocks the STP filters, and they still had some of the old filters that were rated at 94% efficiency and the new ones that are rated at 96% efficiency. ACDelco's are rated at 98% efficiency at 25 to 30 microns. Did not have my reading glasses on, so I could not see the micron ratings on the two STP filters.

Can't find any efficiency ratings for Luberfine filters, but they are always higher for my car. I can find Champ labeled ecore jobber filters cheap.

It all depends. I have the same spec filters as OP, the luberfiners can be found occasionally on rock auto for 1.50-2.15$ each
