I sure wouldn't do a comparative "investigation" of amsoil filters at an amsoil site.
The guy a few posts up made a big boo-boo by throwing a motorcraft and replacing it with a k&n. He had the good and actually spent a premium to replace it with the bad.
I'm open to seeing tests that compare using a standardized methodology.
I use and talk about, but don't sell Amsoil.
