K&N makes AEMs filters. at least last i knew they didumm, K&N and AEM are completely different designs...
fram filters are very cheaply made with a paper filtration system. most oil filters use this design, but frams filtration sucks.Is fram really that bad? or is it just because its sold at Kragen/Autozone/Pep Boys?
I use Fram oil filters and not a single problem from them.
