I don't recall which brands, or models, but I recall a few had been seen to have wavy pleats with uneven spacing. Theoretically, uneven spacing provides less support from the other pleates, combined with a bend in pleating material creates a weak spot that could fail. There have been a extremely nominal report of torn media, but never seen the tear be at the crease.
Interestingly, this is all very academic because the makers of the offending filters have run in vehicles for decades and they don't seem to be concerned about this esoteric issue. I've never heard of an engine failing because of this issue. I think the real cure is to simply do regular OCIs including a filter and you're GTG.
On a related note, I'm always fascinated at the size differential of filters. The Buick 3800 motor filter is barely larger than a teacup. How can that filter sufficiently?? Compare that say, next to a Ford Ranger 4.0 V6 FL1A filter which is about 3x the size for similar engine characteristics!
