Found this information. It sounds like PF48 has been upgraded to the PF48E

I also found a comment that said the PF48E  The E means environmentally friendly and no other difference.

The PF48E primary performance improvement relates to the relief valve design. The PF48E has a compression spring loaded nylon poppet that outperforms the current valve design.



Other benefits:
•Element integrity (collapse strength) is increased by 25%. This is because the nylon cores are perfectly round.
•Filter media, which is unchanged, is no longer potted in adhesive which blocks filtration area at each end.
•Filtration performance (efficiency and capacity) are both unchanged.
•The filter shell configuration is unchanged. Existing cap wrenches continue to fit.
•Hydrostatic burst and impulse fatigue performance are both unchanged.
•Relief valve performance is much improved and statistically more stable.
•Hot oil durability is improved by elimination of adhesive.
•Cold weather performance (-30 C) with dexos 1 oil is excellent.
•Improved level of robustness to water accumulation.
•Nitrile material used in the sealing gasket and the anti-drainback valve is unchanged.
•PF48E filters meet performance specifications as defined by GM Powertrain.
•PF48E filters will be used in OE production in the near future.

I use PF48E as that is what was fitted to engine when new. Not sure what the difference is between filters but I like to keep to original supply where possible. I did have an issue getting PF48E filters a few years ago and could only get PF48. No idea if they are different

Chevrolet LS3 376 c.i 6.2L 430hp V8 Crate Engine

Any one happen to know the difference between the AC Delco PF48 or E
and the AC Delco PF64   they both fit an LS3 crate engine, but have different internal relief V/V set pressure from what I have found posted on some forums.

I'm sure the AC Delco PF48 is the correct filter as fitted on a crate engine
Not sure what the difference is with the AC Delco PF48E

Anyone ever looked it up and come up with any answers
