Not a very good analogy, as the filter supplies the whole engine's oil flow volume, not just a tight bearing or two. Some engines flow 10~12 GPM at high revs.
The question was rhetorical, it was an appeal to sensibility that those louvers, all 150+? of them, are considerably larger than any bearing clearance in the engine, and by a large margin. Even cold oil manages to move through the tightest oiling clearance like a main or rod bearing. When I first discovered louvered filters, my immediate reaction was the same until I thought about it for a bit.
I think the louvers are fine.
Louvers are fine ...
IF they are not closed up like the photos I posted above.
But again, a
Full Flow oil filter supplies all the oil volume to the engine, so saying that closed up louvers are still OK because main and rod bearings are tight isn't a very good analogy ... that was my point. You think those main and rod bearings are using all of the 10~12 GPM a high performance engine flows? They aren't ... there are many other parts of the engine that needs oil flow too. Like I said before ... bad analogy.
