Bought some Purolator Pure One filters this weekend (pn 10241) and saw that the inner core support, the holes are slits, and quite small. Maybe a paper thickness big and that's it. The whole core wasn't stamped this way, just a spiral section, the rest having no holes.
Seems like this would be a restriction especially when cold. I opened up ~ 10 boxes of the same pn and found the same thing. Opened up a few pn 10111 and found the same thing.
Forget what other brand I opened up and found again the same thing.
What's with this change? Anyone else notice this? (or am I late to the party?)
