AEM Cold Air Intake System

AEM 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 kits 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.

Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by 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 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. February 26, 2014
