Ah ..I just got an email from Filter Guy. He's alive and well for all who are interested. He stated that "Champion filters" if they're labeled Champion, are not made by Champion Labs.
Here's what he had to say:
Somone emailed me about a thread on "Champion" branded filters.
FYI..not made by Champion Labs.
Champion Labs makes the "Champ" brand....not "Champion".
If memory serves--those were made by Purolator ( could be wrong) to confuse customers who knew of "Champ".
Also, there were filters made for the "Champion" Spark Plug division labelled as Champion but I think those had the full title on them of Champion Spark Plug (Red/White/Blue).
Or maybe the person who started the thread called the filter "Champion" when he meant "Champ".
But wanted to clarify if someone buys a Champion labeled filter..it's not made by Champion Labs.
I've only ever seen Champion in aviation. Not that I ever deal in aviation filters. I just saw one and couldn't get any of the numbers to xref where I could see some spec's and thread sizes and such.

These are made by Champion Aerospace.
Here's something to ponder. A few of the filters have 3/4-16 threads and are a 3.71" can size. I bet the gasket is a 2.8/2.2 thing too.
I wonder if they're any better than passenger car filters ..or just cost more due to FAA certifications that they have to be engineered and tested to
