WBT, I noticed that too with the Xtra Guard filters. As far as adhesion goes with metal, you can do that without performing any major scuffing. with technology and composites that we have created today, mainly from BASF and 3M, we have created adhesives that are leaps and bound of what they were capable 10-15 years ago. Who here thinks gluing a car together would be strong and better then welding? Aston Martin is big behind building their cars and using a bonding agent instead of welding on their cars, and these adhesives are sometimes stronger the then the metal/composite itself!! It all comes down to cost in the end.
Fram's are marketed for the Box store idiots who are looking to just do an oil change, and as I said before, Fram has built up a lot of followers thanks in part to their advertising.
If Fram was so good, why doesn't any top NASCAR team use them? why Wix? Quality, plain and simple.

The end caps may not deal with oil bypassing, but you have to realize they play an integral part to the structure of the filter. What resists twisting, and deflecting less, a piece of cardboard, or a piece of steel? Enough said. There is a reason why top shops, quality restoration, and engine shops prefer Wix/NAPA over Fram. I can go all day, but I'm waiting for Honeywell's spokesman to respond to WBT and me.
