In my opinion you start splitting hairs when you talk about which filter is the best between two quality filters (K&N and AEM). NOTE: I am talking about filters, NOT intakes. Anyway, I like that you can clean the K&N and “recharge” it. I would be surprised if either one yielded higher HP ratings than the other.

There was a thread in this board a WHILE back, pointing to a site comparing filters. They used a vacuum cleaner and stuck a filter in the end of the tube as a test. They were comapring air flow and filtration ability (not all filters air the same way). I think the candidates were, Apex, Blitz, HKS, K&N, and some others. The one that came out on top (having flowed the most air and filter the most dirt) was the Apex-i filter. I think the worst was the Blitz stainless steel filter then HKS. The Blitz one was nasty, it had all this gunk built up at the end of the vacuum.

AEM used to use S&B filters back in the day. Then they switched to K&N filters. I believe they are still using K&N manufactured filters, but the AEM filter is special due to the redesigned air horn. I think it is the part that extends out like a small pipe. I would just get the new AEM filter since they don't lie about proven hp gains. I also like their new polished CAI (its powdercoated clear and looks shiny almost like chrome).
