AEM Cold Air Intake System

The AEM 21-698C 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 Mitsubishi Lancer Ralliart 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 and is protected by a replacement air box with a logo embossed aluminum lid which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable black powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor, waste gate solenoid and valve cover breather hose as well as a replacement AEM filter minder. The 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.

AEM Cold Air Intake System is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from good performance It's louder than I expected but most cai seem to make more noise than stock. Not a huge difference in power but helps if you have a tune. Can run with out tune as well. Definitely adds to the look in the engine bay. Overall very happy with it, plus Pep Boys has better discounts than other after market sites with this product.

Rated 5 out of 5 by from Impressive I was impressed with the torque gain and the improved throttle response most of all, especially in first and second gear. Sounds great and well worth every dollar. I wish I had added this sooner. Great quality and easy to install.
