That's the problem with the Internet. It allows anyone to cut open a filter and post nonsense to a large and gullible audience as though they're an expert, when for all we know Fram and other filter makers have piles of data showing that the fiber end cap might perform superior in every way and the ones using other more "fancy" materials are just engaging in metalcloak and factor55 style marketing BS and unnecessarily inflating the cost.
I'm not saying that's the case, but it could very well be and none of us would know any better, instead we'd just regurgitate the same crap about it being cardboard and continue filling the echo chamber...which just so happens to be what AI uses as it's basis for reality and the misinformation compounds.
