Custom High Flow Washable Filter w/ Velocity Stack: This washable filter is the last filter you’ll ever have to buy. One of the special characteristics of our filters is the full or modified velocity stack. This allows the air to curve around the edge of the filter and enter the intake tract without loss of velocity, resulting in more power. We have conducted tests where there is more airflow with a full-velocity stack filter than with a straight tube and no filter.
