AEM Cold Air Intake Systems are designed to produce horsepower and torque gains. They replace the restrictive factory airbox and air filter to give you better performance and better engine sound. AEM cold air intakes relocate the air filter outside the engine compartment so cooler air can be fed into your engine. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber for more horsepower and torque. AEM Cold Air Intakes include an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration, and performance while allowing easy oil-free cleaning. They include a mandrel-bent aluminum intake tube 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. This Air Intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Dave from Vail, Arizona

I bought the AEM system because I previously had one installed in my Scion and ran it without maintenance or problems for over 80,000 miles. This product is all high-quality metal, no plastic, and should last forever. Not enough experience yet to rate performance, though I suspect my fuel economy is a bit better. The installation process was straightforward though difficult because the installation tolerances were so tight, requiring several loosen-retighten exercises to make it fit. All in all not an easy install, but certainly doable and requiring only some extra muscle and creativity. End result good looking and very stable.

I love this intake but I just wish the heat shield covered the filter a little better.
