This is the AEM DryFlow Air Filter. AEM Dryflow air filters are developed in collaboratoin with K&N and have adopted some of the best elements of cotton air filters into a new generation of synthetic Dryflow Air Filters. This filter features three-dimensional filtering medium which uses both depth loading and a structural screen wire which enhances the airflow capabilities which also makes the filter easy to clean for future servicing and use.
This filter has a 6" base outside diameter with a centered 3" flange inside diameter with a height of 5.125".
This particular filter is also a component found in certain AEM intake systens, however, it can be used with other intake systems to make as a great replacement filter.
