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.

Very noticeable change in torque; great company. Installation was as easy as it gets, plus it got here a day early
Overall an easy install, can do everything from up top, and sounds and performs nice. Also takes care of the 2 gear boost lag when really pushing the car.
Could wait to install this, once it arrived. It went on that evening. Couldn't have been easier. Power gain and drive ability was instantly notice and continues to impress me. Thanks AEM for a great product.
Could not be happier. Easy instal with great results
Great sound, easy install, and noticeable gains. Looks great in the engine bay.
Great job AEM
Took around an hour for the install, but I blame Subaru. The clamp on the lower intake hose was installed pointing downward, causing me to get under the car and remove part of the wheel well to loosen it. As for the kit itself, great, detailed instructions, everything fit together perfectly, kudos to AEM. This has been my second intake kit from AEM and will continue with them. One thing to be said is that both Mishimoto and ETS include their own lower intake tube, AEM uses the factory one. Which is why AEM can typically be installed without having to get under the car
Great Product/Fast Shipping
Very nice quality with easy install. Sound alone is worth every penny. Turbo spool is so much nicer and gets rid of that nasty 2 gear boost lag when really opening up the throttle. Over all great product.
