Yeah, AEM is a division or subsidiary of K&N. The box had a K&N shipping label on it. The "I like messing with stuff like this" was a large part of it. I do perform my due diligence before ponying up for things like this, though, and the AEM DryFlow was tested in 2007 against K&N's own oiled gauze filter, aFe's oiled gauze filter, aFe's Pro Dry S (dry non-oiled) filter, and an Airaid oiled gauze filter by an independent lab, Southwest Research Institute. The AEM performed best @ 99.47% efficient using ISO 5011 fine dust test procedures. But the AEM also was, as expected with the better filtration, slightly more restrictive on air flow than the others.
