Here is a sample of the "who makes various filters" list, some maybe be surprising, but build houses do offer various grades of build so each sub-brand isn't necessarily the same as the others made in the same build house, K&N catches a LOT of flak (warranted and unwarranted) for their ridiculous marketing fluff, but, they do make decent products (for a price lol):
Fram and Champion are 1 company now, like Metzler and Pirelli.
Fram
Fram Extra Guard (std)
Fram Tough Guard (different media?)
Fram X2 (Silicone ADBV, Fuzzy media)
Fram Extended Guard(same as the X2)
Mileguard (Jiffy)
Honda (although some are alleged to be made by Filtech)
Chrysler line up except for the Cummins
Penzoil
Deffense
Canadian Tire
Champion Labs
Bosch
Car and Driver
Deutsch
Mobil 1
STP
SuperTech
K&N
Valvoline filters
Mighty
Service Champ
Lee
AutoZone Value Craft
Some AC Delco
VW (some)
Warner
Luberfiner
Trust
One I'm going to try is the Amsoil filters, it has some legit better technology incorporated into the media which shows superior filtering in the Beta tests below 20 microns. EA103 seems like it will fit, ordering one to test.
