Product Description

AEM pioneered the Cold Air induction system for sport compact cars in 1994. A Cold Air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horsepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and this tuning allows us to deliver the maximum power gains throughout the entire RPM range. We also monitor fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light. Our Cold Air systems are dyno-proven and tested against the competition with the goal of creating more useable power than any other system of their kind. Every AEM Cold Air induction system features the highest standards of construction and we are so confident in their fit and performance that we guarantee them for the life of your vehicle. All AEM Cold Air systems are either 50-state legal or pending (excluding "Off Road" and "Hybrid" systems), include a lifetime DRYFLOW Synthetic air filter and come with a limited lifetime warranty.

Amazing Product, Does exactly what AEM says it will!
By J. Hall
Let me preface by saying I am not a knowledgeable car guy. I bought this at the insistance of my buddy who is. I have seen a noted increase in MPG as well as my car running with a little more UMPH. I love this add-on and it only took me an hour to install. An hour install for a non-car guy is pretty good. I would highly recommend this intake and the brand AEM as they sell a great product! Came very well packaged and the powdercoat finish looks amazing. Makes the engine look very tough!

Installation could be more streamlined
By Jon
I am an auto technician and have dealt with many air intakes. This system may be a great power addition (although not felt by me) but the installation process required removal of the left front tire and the fender liner. So every 5,000 miles when the filter needs to be cleaned, that process will have to be duplicated. I thought that was a little bit much considering there wasn't much of a power addition to the engine. As far as quality, I believe this to be on par with most aftermarktet intakes. It ships with all new band clamps and silicone sleeves for hookup.

good purchase
By brianmk
it added a nice growl tot he sound of my car. perfect fitment: it can be used as a short ram intake and cold air intake, by removing the last pipe. And very easy to install.

In the end its worth it.
By 04 RSX
Watch Video Here: http://www.amazon.com/review/R1LKOV0FPH5Q18 Bought this for my 2004 type S and am overall very happy with it.The installation instructions are surprisingly detailed in some portions, and completely lacking in other portions. (It jumps from removing the inner fender wall and taking the windshield washer bottle off, to the entire tube being installed already and mounting it in. (You route it through the wheel well if you were curious, but I found this out on my own.) As far as a cold air intake goes, the difficulty on this particular one is probably an 8 out of 10. It took me and a buddy about 5 full hours to get it done. (Probably 45 minutes of that was wasted time looking for tools) but it is a very in depth process as far as an intake goes.It does require cutting of the inner fender plastic on the drivers front wheel.(nothing crazy, I did it without even removing the fender plastic) It may be smart to have some extra fasteners at your disposal for when you accidentally break them in the process of removing the wheel well plastic. And if you're buying the intake for show you will be sorely disappointed. of the entire 24+ inch system, if you install it correctly you will have about 4 inches of visible intake, and the rest is hidden unless you really look for it. I was okay with this, because the paint these intakes are painted with is very fragile and I royally scratched the %@#$ out of my intake while trying to wiggle it into place.Performance wise, there is a very real difference in sound of the engine. If you're driving slowly and not really hitting the gas too hard, you're not going to be able to tell a difference, but if you hit the gas hard the engine has a very nice low growl to it. My friend compared it to my Suzuki650 which had a two brothers pipe on it. The car is not too loud at all, but definitely noticeable.Power wise, all I've really noticed is a bit more low end torque, which is what these cars seem to lack a little. So the torque before you hit the vtec is actually improved a bit. Also there is a much more noticeable sound difference when the Vtec kicks in.The only issue, that I see...The intake is very very low to the ground. It sits right behind the lower vents on your front bumper. About 12 inches off the ground. If you're worried about sucking up water, grab yourself an Injen HydroShield. That's what I did. If you're looking for something more showy and less performance (also a bit safer) check out the Injen V2.Overall very happy with the product.
