Fram Titanium is no longer metal screen backed. Ultra, Endurance, Titanium ALL are synthetic *blend* media.

I was surprised to see it has lovers. I thought the FE filters had wire backed media and holes in the center tube…

The Fram Endurance is wire back, but I think they normally have louvers. At least all the FE spin-ons I've seen have louvers.

As the Fram Endurance is made by the Champ Labs division of FB, having a louvered tube would make sense. Thus far haven't seen any though with ecore like some Royal Purple have shown.
