The AEM 21-792C 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 Honda Civic 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 placed into the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The air intake tube 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 mass air flow sensor and engine vent line. 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 easy to install with commonly available tools and it 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.

I am very satisfied with this purchase I do not regret it at all. It does what it says and adds a growl to your car. Definitely recommend this product.

The intake does what it should. Sounds a LOT better than stock. it sounds deeper and has more Grunt. I do feel the slight increase in power. Vtec engagement is now more audible when it kicks in. The installation wasn't easy, had really sore fingers afterwards, but once all done, it was worth it. I definitely recommend this product.

This intake gave my car a boost in horsepower, but best of all it made the sound of my engine accelerating a lot deeper. I love the way it sounds when I hit high rpm's.
