While that's generally true for the spin-on assembly line filters ..I don't know if Champ actually makes a cartridge filter. If they don't ..there's no bid to be bid.
While they may have been provided by Champ Labs ..that's no assurance that Champ Labs manufactured it. People were pulling identical cartridge filters out of Fram and many other labels for a good while when the market would only support one or two manufacturers for very few rolling automobiles that needed them.
Champ may indeed be making them now - however
No filter man makes all filters. They all employ filler stock from competitors. When a sales rep goes into an establishment, he has to have the ball always in his court at providing the service.
