It is fairly easy to make a filter that has good flow characteristics; however, the real trick is stopping the dirt while improving the airflow. This is what separates S&B's New Dry Filter from AFE & AEM equivalent. In our opinion, AFE and AEM's "cleanable" claim comes at a price, which is poor filtration.
