1. I've cut apart both. I rank them on-par.
2. Search Bill in Utah's post, he had a VERY defective WIX.
3. Check the WIX China thread currently a few threads below this one.
4. Donaldson and Fleetguard are not specialty filters; AMSOIL and Royal Purple, yes. I can walk into any transport dealer and get either of the former. Readily available, yet premium construction, unfortunately their selection of automotive filters is more limited than that of WIX or Purolator.
