I have no idea about the Wix XP/Napa Platinum efficiency, as it is a relatively new filter (they just released the Pentatsar cartridge every recently). It is probably not as efficient as the Ultra, but it will be stronger due to the wire backing.
Well, I tore apart the Fram Ultra filter, and guess what? It is indeed backed by metal mesh, and it is strong as heck! I had to tear HARD to get it apart, and it only campe apart where it attached to the plastic end. I coudn't tear the pleats themesleves where the metal mesh was attached. My confidence in this filter is higher than ever. It is one tough SOB. I'll try and post a pic, but it will probably show up as a link.
Also, there was no compromise, whatsoever, even where the worst of the twisting occurred. This engine couldn't generate the pressure to tear this thing apart, if it wanted to.
On the latest Fram UG installed, I didn't tighten the cap as hard. Maybe that was the issue. We shall see, but in the mean time, I'm going to keep running these.
