It is a fantastic thread, with some great cut open filters, some nice data, and all the stuff we like seeing here. But, "best" is pretty darned subjective. For me, the best filter would have features that include the large catalog of Wix, the cost what I pay for Bosch Premium or certain Wix part numbers, filtration of the Bosch Premium or Fram Ultra, the coil spring of the Wix or Hastings, the silicone ADBV, the thread end bypass, and the availability of the Fram orange can, a metal centre tube and end caps, and careful attention to detail on QC matters, and complete backing by the vehicle OEM. Of course, such a filter doesn't exist, and I have to sacrifice one or more features, no matter what I purchase.
