Yes, that is one slight advantage of using an over-sized filter. As the media area goes up, the delta-p will go down if the media and flow rate stays the same.

This has been linked to dozens of times, and clearly shows that PureOnes are not restrictive. I mean how could you even conclude they were "restrictive" without a real test with instrumentation like this one that Purolator did with special equipment?
PureOne Flow vs Delta-P Data
This one has been linked at least as many times: Pure One restriction While everyone can acknowledge the data from the the ZeeOSix link, Purolator themselves make the assertion that Pure one is overly restrictive in the second link. Surely this contributes to the perception that P1 is overly restrictive. Just sayin...
As far as AC Delco changing the construction of the PF48 goes, this hurts my heart just a little. The PF48 has treated me well over the years, and didn't really seem like it needed to be "improved".

My local Chevy dealer has a ton of the PF63 oil filters left (non-ecore) design and is willing to sell me them CHEAP! I told them to put a pack aside for me. The AC Delco non e-core filters are extremely good filters and for the price, you can't beat em.
Just changed the oil in my boat and the ACDelco PF454 I got is an E-core as well. Very disappointed, to say the least. I installed it anyway. Last time.

I doubt any center core in the 'old metal design' contributed hardly any flow resistance. The base inlet holes and the center core holes are the least of the resistance, it's mostly in the media.
