I won't run Wix or Napa until I see their filter efficiency and only if it is competitive. Fram XG is 99+% down to 20 microns and M1 is 99% down to 30. Anyone know the numbers for Wix?
One thing about the Pentastar is that all the filters posted on here buckle, even the ultra! The Ultra for this application uses a plastic mesh instead of the usual wire backing. The XP/Platinum uses a wire mesh, so it should be stronger and not buckle
They don't buckle, they twist. Buckling would be creasing. It usually happens because the cap is overtightened, which is easy to do. I will tell you that the Ultra is STRONG. The bond of the mesh to the media is incredibly strong. The media itself is super strong, too. I tore one apart and it required pliars and a shocking amount of force. It shruggs off even the greatest pressure/force the Pentastar can throw at it. Also, I've not torn one apart yet, but the Mobil 1 supposedly has wire mesh, too. Once I run one, I'll tear it apart I'm hoping it is as strong as the Ultra, because I have 12 of them on deck! Lol.
