I'd like to see Fram beef up their non-metallic end caps, more like what they do on the OEM Honda filters to ensure they do stay flat and ridged. I think that some people freak-out when they see a warped end cap on a Fram.
IMO, Fram's efficiency and debris holding is very decent for the 3 levels of oil filters that they produce (EG, TG & XG).
