This info is quite clear and found in the S&B provided ISO 9000 testing report. It's a nice to twist reality to make sales.
Their test did prove the oe filter filters better but it also proved the s&b flows more air. The statement about the stock filter being good up to 500hp is misleading because it really limits you to about 500hp. There are guys out there with dyno sheets to show that the s&b filter got them to and above 500hp. Where the oe was holding them back. One that I read but didn't book mark so I can't provide a link was the highest hp he could achieve was in the mid 400's but then changed to an aftermarket cai and broke 500hp. So yes you will have to clean it frequently and no it won't filter quite as good as factory but no matter what hp level you are at the cai will help make more power.
