AC Delco PF 48 Variations

[Snagglefoot]

Here is a screen shot of a Rock Auto oil filter page showing three versions of the AC Delco PF48 filter. Prices are toggled to Canadian dollars so just multiply by 0.8 for accuracy. Any comments on the three versions, good, bad or ugly? Thanks.

The PF48E is priced as a 12 pack. The PF48R is a higher quality and performance version of the 48.

Has anyone cut open any of them?

ACDelco is shifting their naming strategy with filters.

Historically, filters with an "E" at the end were E-cores and those without were not.

PF48E = E-core
PF48 = Not an-E-core

That is changing and the "E" is being dropped across the filter line. There will just be a PF48 now and it will be an E-core. You can identify the change by the new-style ACDelco box that's mostly white (instead of blue) and has the "Genuine GM OE Original Equipment" logo. I believe the 8-digit P/N changed as well and is not the same as the old PF48 or PF48E.

UPF48R is the "racing" version of the PF48. It is and always has been a non-E-core filter.

Double checked the 8-digit P/Ns:

Old PF48 non-E-core = 89017524
Old PF48E E-core = 12690386
New PF48 E-core = 12710960

I'm sure it'll take a while for the retail supply chain to catch up, so you'll likely see some mish-mash of them on shelves together.

Here is that non E core 89017524 still available at Rock Auto apparently.

I’d just go with the UPF48R since it’s their premium offering. Heavier construction
