The usual suspect in such a case is that Wix is putting a thread end bypass in such a part number. That will take up space, which is certainly more noticeable in a smaller filter.
Thats one of the reasons why cartridge filters beat canister ones IMHO. Can inspect cartridges for quality/intact construction before-hand. You don't have to cut them open to find out (AFTER usage) if it is intact, AND you don't waste metal. Engine makers should all convert to cartridge-only setups. It wouldn't be hard, even with current canister designs, as you can put a permanent housing where the canister now goes, just insert cartridge. A greener solution because some of us don't want to waste the earth's resources.
One example: Wix's NAPA Gold 7327 cartridge (BMW '07 530 N52 six) has obviously more media area than the already-decent Mann-Hummel HU-816x, and Wix puts some glass fibers in there as a bonus.
The other day I ordered a WalMart.com twin-pack of Mobil1 Ext Perf oil filter cartridges for my '11 Camaro 3.6L six and immediately noticed the pleats were very wide&uneven all around, like they didn't use enough media and had to stretch it (bad batch). I returned them. Had they been inside a can, I would have never known.
