That box design has been discussed before ... consensus was that it's a new design of the box by ACDelco.

What you mean? If you're talking about the plate with the big holes over the base plate, the ADBV seals on the base plate, not that plate covering the base plate.Just me? ................... that ADBV serves no purpose with the punch/production techniques used on those holes and the areas between

Always love me a good delco. Thanks for sharing,
Happy new year

I'm going to break new BITOG ground here....with an observation.
I think the notches in the "wings" of the bypass spring (9th pic) allow hot oil to pass more than they'd allow cold oil too.
Ergo, I think this setup bypasses cold oil as a matter of design.
As the oil heats up, the resistance goes down and the oil gets filtered.
Whatcha all think on this New Year's Eve eve?

Not really seeing how the notches would let oil into the center tube? They're on the far edges, oil can't get anywhere close to the center. Guessing this engine has a block mounted bypass?
It is GM's attempt to be more "global" (i.e., to sell more stuff to more people in more places). It's interesting that they want to enhance product security but the filter boxes are not sealed, thus allowing walmart shoppers to swap parts between boxes...

Not a good champ design. I miss the classic design that performed flawlessly. I reiterate that the E core takes up too much space making a small filter way too small for anything more than a little Kawasaki powered yard tractor.
And ... if I understand @LvR, the two-step FRAM-ish, ugly baseplate punch and stamping is suspect.

I ordered an AC Delco oil filter (Honda sized) and thought it was strange to have Asian lettering on box.
While there are some exceptions, pretty typical Champ Labs oil filter construction now. Ecore with metal caps.
Thanks for c&p.

That's just the leaf spring to keep the filter guts tight. This filter has no bypass valve. As bullwinkle mentioned, probably specified for GM vehicles with the filter bypass built into the block.
