Does the design actually help to filter netter or cause oil to filter more even throughout they element? Otherwise why couldn't they just wrap media around the core 2 or 3 times without crimping in pleats. Does the crimps or pleats contribute to structure support or strength?
Why pleats

As mentioned, pleats increase the surface area.
I've wanted to mention this for a while now....
I remember seeing a cutaway oil filter at a Toyota dealership where the element was a series of folded up squares.
Accurately describing what I saw would be difficult.
The square folds were "stacked and staggered". 'Twas downright attractive.
It appeared the oil would go through multiple layers of media.
That was in the late '70's when I got my first car, a 1970 Toyota Corona Mk.2 wagon. Kira

I think I can visualize what you mean. If so, then it seems like it would be difficult to manufacture as cheaply as pleated media and maybe be more failure-prone. What are your thoughts, based on what you saw?

You get more surface area, each oil "molecule" only has to go through one layer before it's "free" and goes off on another mission. If you wrapped it like toilet paper it would have to go through 30 layers. There's never ending amateur evaluation of the right number of pleats, as too many pinch together and don't let anything through. Too few are just cheap and too uneven are sloppy.
Incidentally TP is used in bypass filters because it's very thorough, but very slow and can't possibly do the whole flow.

@wemay, that Toyota filter is awesome!
I also like the squiggly Purflux cartridges.

Like the weird Japanese Denso foam ones, they look different but no evidence they are any better or worse than traditional filters.

I don't know how old that picture is, I remember seeing a cutaway like that when I used to take my old FX16 GTS in for old changes at the dealer in the late 80's/early 90's.
What's interesting is that there's not metals endcaps..it looks like it does have a type of treated paper, or fiber endcaps. Guess Fram wasn't the first one to introduce paper endcaps.

I don't know whether i like it only because it's different or not. Lol. By i do.
