The AEM Dryflow Brute Force air filter exceeds the airflow requirements of “deep breathing” big engines under tough, dusty racing conditions. Brute Force Dryflow filters have a special filtering media that is tougher than the standard Dryflow filter media, to hold up under harsh environments and repeated cleanings. These filters will retain their shape and performance even after the most severe abuse. To prevent the filter from collapsing from flow demands, Brute Force filters also have a special lightweight, mineral-reinforced plastic cage that maintains the element’s structural integrity. The airflow capacity of Brute Force Dryflow filters far exceeds that of the stock engine’s requirements, so you have plenty of leeway for racing engine modifications without having to worry about exceeding the flow capacity of the filter. But airflow and durability haven’t been gained at the expense of filtration capability. Brute Force Dryflow filters have the same excellent filtration capabilities as standard Dryflow filters. They capture up to 99% of contaminants, extending the life of engine rings and seals. Finally, they are just as easy to clean as the regular Dryforce filters, and like all AEM Dryforce filters, require no oiling.
Brute Force filtering element:
The AEM Dryflow Brute Force filter is constructed of a unique non-woven polyester-based filter media supported by a lightweight mineral-reinforced plastic cage. 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. The plastic cage helps the filter retain its shape, eliminating the chance of the filter collapsing from flow demands. The Brute Force filter is a favorite of racing teams competing in rough, dusty conditions. Cleaning is easy; simply tap the filter a few times to 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 Brute Force filter requires no oiling, so there’s never a chance of over-oiling. The Dryflow Brute Force filter is extremely durable and will withstand almost unlimited cleanings.72.00Brand: AEM Part Number: 21-2267BF UPC: 024844285331
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.AEM® 21-2267BF - Oval DryFlow Brute Force Air Filter Reviews (10)Customers' rating: 5 OF 5APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITYGreat Product| Posted by Michael M. | 2007 Chrysler 300 (Eagan, MN)
The AEM filter is definitely an improvement over the stock paper filter I had. I could feel a difference in acceleration and a bit more sound. Plus, this filter is extremely easy to clean and maintain.Was this review helpful for you? YesNo(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITYMeh| Posted by Jason M. | 2010 Kia Soul (Kent, WA)
Car seems to have a minor adjustment in acceleration smoothness. Its nice to know that I can just clean this bad boy though. The other thing I noticed was a 1/2 mpg gain, and when paired with my Amsoil fluid change giving me 1 mpg that's a nice stepup. No noticeable horsepower gain, no nifty intake growl. Just a very nice drop-in that won't mess up your sensors. This filter is however kinda heavy.Was this review helpful for you?

I bought this product as a replacement product for my 2010 Xterra's CAI and it far exceeded my expectations. First and for most it corrected my check engine light problem. Second, CARiD definitely has the cheapest price for this product anywhere and shipping was fast though. I wish I knew they had Miltary Discounts so I could have gotten it cheaper. Very good product very pleased. Thanks.Was this review helpful for you?

Installed the dry flow filter about 500 miles ago, no notable improvements in mpg's or torque. Air filter took 30 minutes to install but thats due to manufacture's set up of OEM air filter box. Overall its well worth the investment. Cheaper than replacing cotton filters every year and much better quality. $60 for filter and cleaner versus $10/year for OEM replacements. If you are planning on keeping your car for more than 6 years this product is worth its weight in gold. No added performance just a economical decision in the end.Was this review helpful for you?
