I'd be curious to see the internal construction difference(s) between the "high flow" Mazda filter and the other Mazda not recommended from whatever source. I suppose Mazda can do that for their filters, but not for other brands.
I say that because if Mazda "requires" use of a certain filter only, i.e., the "high flow" OF, then Mazda has to pay for it. That's part of the Magnuson Moss Warranty Act. Guaranteed Mazda not paying for an oil filter for anyone.
Personally, count 'me' as skeptical about the "high flow" oil filter. 'To me' reads like something to get owners to buy the specific Mazda OEM oil filter only. My.02
