So here is an Australian filter brand Ryco filter dissection. Thought id make an account and put this in here as i had yet to find a post of a Ryco. The Z9 is 40um @ an unknown efficiency level and is equivalent to Motorcraft AFL1 (Australian part number) and FL1A (American part number)
Filter was used with Penrite HPR30 mineral 20w60 oil for 4599km, Driving style was harsh, some highway to the track then run at the drags. in a NA 250ci 6 cylinder Australian ford crossflow engine. The oil suffered some breakdown/reduced viscosity after the car was run at the drags and has since been changed to a full syn.
The filter was well built, the can was of reasonable thickness (sorry did not measure). It used a coil spring type and silicone ADBV. The filter has steel ends and the bypass valve is in the top of the filter end cap.
Filter medium is paper, the pleats are evenly distributed and all straight. With a steal crimp joining the medium. There is no gap in the glue that connects the end caps and no signs of abnormal wear or failure of any part/component.
The filter is well built and i could not fault it. Cost less than $10Aus.
