I went there to check it out and was overwhelmed by the bazillion pages of stuff. I couldn't get past the first page, mostly because of time constraints. But Birch, if you've read all of that stuff and have some cool inside info on air filters, please let us in on it. I'm still messing around with the stock filters on our 2004 400's.
