The AEM 21-8217DC Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle’s restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Dodge Caliber, Jeep Patriot and Compass models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the IAT sensor and crank case breather hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Nate Pearson from Davenport, Iowa
February 23, 2015 - Part 21-8217DC
The product provides solid power gain that is very noticible in daily driving. You will notice an appreciable increase of speed in merging situtiations. The fact that the filter to the intake is right in front of the drivers seat may prove to be to noisy to some people under wide open throttle conditions. Installation is also challenging on a Jeep Compass because of the tight engine bay. It will just take a little bit more time because things are harder to get at.
