I used to work on heavy equipment before I started rail roading. All our service manager would order was Wix filters. After seeing some of the cheepies in the field fail, namely Fram, I will never put anything but Wix on my vehicles! all one has to do is cut open a Wix and do the same to a fram and you will see why. externally, the Wix has more return holes, Internally the wix media is twice as thick as the Fram, the Wix uses a coil spring, the Fram a flat spring. To me the fram is an accident waiting to happen! For the extra buck or two that the Wix costs, why take a chance?
