AEM Air Intake Systems are designed to produce massive horsepower and torque gains as well as better engine sound when used as a replacement for the factory airbox and air filter. AEM intake systems are designed, tuned, and dyno-tested to fit specific cars and trucks. These air intakes usually include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. Most AEM intake systems use mandrel-bent aluminum intake tubes, powder coated heat shields, and high quality hardware designed to reduce restriction and reduce intake temperature. The design and components of each intake system vary so consult the installation instructions for more information on the contents of each part number. AEM manufactures a variety of intake kit styles including short ram intakes, cold air intakes, dual-chamber intakes, Brute Force intakes for trucks and SUV's, and Brute Force HD intakes for diesel applications.

Product Reviews    Review part 21-450B

Super easy to install. Great sound, & quality. Works excellent combined with other engine upgrades. Have this on my 01 ZX3. A must have!
Alberto, Lancaster, California
I have to say that this DryFlow air filter has been a worth while purchase for me. I installed it in my 2008 Ford F-150, and immediately noticed the response. I don't have to put my foot into the gas pedal any more. What I do need now is the full intake set-up which I'm glad you can do with a self installation. I had folks pushing me towards the K&N oil filters, but I believe this is a better product for the engine. I'm going to pair the air intake with an exhaust upgrade just to make sure I get the best output, and mileage. If your looking to upgrade your filter or intake system I would recommend this product.
