Bosh 3331 and ACDelco PF48E cut open.

[ls1mike]

The Bosch was run for 5200 miles on the Grand Prix. The ACDelco for 5000 on the Malibu.

I thought the Malibu needed a AC Delco PF64 filter not the PF48

Either one will work. Has to do with the bypass I believe. The both have Mobil 1s on them now.

oooo a red dot on the AC (it's a black dot on Fram's own filters and most ecores, too)

Surprised to see them still made by Purolator, since Bosch pulled out of the company.

Not bad looking acdelco. Mite consider it on the oil change after next on my 2015 2.5L malibu.

the e core looks like it has better flow but that is why gm said they went with the new e core anyway

Bosch divested their half ownership of Puro US as few years back, as they did several other companies during the same time frame. But they've seen fit continue to send their US filter biz to their former Puro US partner, Mann&Hummel. Both German based companies, might be factor. Just speculating.

For the BP, pleating could be better in the one pic. That said, looks to have held up for the ~5k oci.

As for the ACDelco, what I'll refer to as the 'made for GM vehicles ecore hybrid.' GM specs for newer GM vehicle with filter integral bypass the ecore nylon cage. But uses the Fram style dome end poppet type bypass. No nitrile combo valve for GM. This one looks fine.

Thanks for pics.

How come the ecore has 'tons' of exposed filter in/around the plastic center tube, but many filters with metal center tubes seem to barely have any holes/louvers to flow adequate oil?
