I've heard it from someone who works on the air filter line for one, and for 2... my BOX says "AFFINIA Group" on it (carquest red), yet the WIX style filter (carquest blue) says "WIX Filtration Group" on it. Nowhere on the RED box does it even mention "Wix Filtration Group". Shoot, even people from here who worked or still work for WIX even specify this... "There is only ONE Wix filter, the others are NOT Wix filters, they are affinia".
Here is a direct quote from one:

Just because we make it, does not mean it is a Wix Filter disguised as another brand, although some are.

Oil Filters
Oil is the life-blood of every vehicle, and oil filtration plays a vital role in protecting engines from premature wear and potential failures. From NASCAR tracks to construction sites and everywhere in between, Affinia oil filters are purposely "over-engineered" to handle a wide variety of fluctuations in flow and pressure, while withstanding vibration, high and low temperatures and constant spring-load pressure.
