I have the feeling the failures on the K&N and Hi-Flo filters with the 17mm nut spot-welded to the case are due to overtightening, especially with air or electric impact guns.
Here's a pic inside a Hi-Flo filter. Filter cartridge is actually smaller than the ones from the original CB750. Not much real change in 50+ years, but the spin-on filters cost more than twice as much, and there's such a waste of materials.
