When used properly and at regularly scheduled intervals, AEM’s Filter Cleaning Systems will ensure that your AEM filter element lasts for the life of your vehicle. AEM has two filter cleaning systems, one for our discontinued oiled-type air filters ONLY (AEM’s Turbo-Flo), and one for our revolutionary new DRYFLOW air filters. The part number for the DRYFLOW Cleaning System is 21-110, and the part number for our previous-generation oiled filters is 21-100.
