I have been disappointed in Napa and Wix filters of late. They are one in the same. Plastic end caps and threads on a fuel filter just does not cut it for me. I traded them out for a Fram that is built much better.

Why do you hate plastic end caps? Do they prove better filtering, longevity etc? I could careless what they are as long as the work in UOA's.
Kubota air filtes, as least my Bx24 and BX22 came stock with a fleetguard air filter. I buy NAPA now.
