The AEM Dryflow reusable air filter is precision-engineered to be a direct replacement for the disposable factory air filter. It’s constructed using a durable urethane sealing lip to help ensure a positive, air-tight seal in the factory airbox. AEM’s Dryflow, non-woven, oil free, synthetic filter media is incorporated into the filter which allows for easy cleaning, durable service, and excellent filtration. While the Dryflow Air Filters is designed to increase Horsepower and acceleration, the synthetic filter media means it’s also washable and reusable so it never needs to be replaced. When it does come time to service the filter, cleaning can be easily completed using AEM air filter cleaner. Cleaning is performed by following a simple four step process and the filter does not require oil.
