  • Easy to clean – no oiling required
  • Durable - able to withstand almost unlimited cleanings
  • Guaranteed for the life of your vehicle
  • Proudly manufactured in the USA

AEM's DryFlow air filter offers the best of all possible worlds, increased airflow to the engine, optimal filtration for long engine life and easy maintenance. First let's talk about airflow. Every DryFlow filter is designed to exceed the engine's airflow requirements; not by just a little but by a wide margin. This allows you to make engine modifications that increase engine airflow without having to worry about exceeding the filter's airflow capacity. And the DryFlow filter performs under real world conditions. It flows almost as well when it's dirty as it does when it's clean, and its unique non-woven filter media is designed to actually shed dirt under engine vibration, unlike cotton-gauze filters that retain dirt. But don't think that filtration ability has been sacrificed for airflow. The AEM DryFlow filter captures up to 99% of contaminants, extending the life of engine rings and seals. Finally, the DryFlow filter is a breeze to clean. Simply knocking the filter a few times will remove excess dirt from the filter pleats, and the actual cleaning process is simple. Most importantly, the DryFlow filter requires no oiling, taking the guesswork out of servicing.

The AEM DryFlow filter is constructed of a unique non-woven polyester-based filter media supported by aluminum screen wire for rigid structural strength. This filter media doesn't require oil to filter and trap dirt and contaminants, and actually sheds dirt under engine vibration, unlike cotton-gauze, which holds onto contaminants until you clean the filter. When it's time to clean, simply tapping the filter a few times will remove most of the dirt from the filter pleats. Then spray the filter with AEM's environmentally friendly, mild, all-purpose cleaner. Rinse the filter with clean water and allow to dry, or blow dry with compressed air. Best of all, the DryFlow filter requires no oiling, so there's never a chance of over-oiling. The DryFlow filter is extremely durable and will withstand almost unlimited cleanings.

John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They're the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
