    Will It Fit Your Vehicle?


    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 horesepower 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 no company on the market can tune an inlet as well as we can. 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 to create 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.

    Sweet Intake System!

    This is a awesome intake system! It's got a great throaty sound especially in the high RPM's. I have noticed great gains of power in the RSX. Install took about an hour and a half, wasn't to bad.

    AEM cold air

    Was not that hard to put on, only took about 20 min to do. Good gains, i like it way better than my AEM short ram. I'v only had it for about 3 weeks so far it's been an awesome bolt on. It really helps in higher RPM's

    Great Product/Great Service

    Fairly easy to install, it just sucks to find out the previous owner had broke part of the bumper and epoxied it together. (making the bumper not removable) Other than that great product, a little bit in power gain but definitely sounds amazing around 2k-3krpms. And great service. I received mine within 2 weeks.

    aem cold air

    installed this on my girlfriends little rsx, soumds better than stock, good power gain, mostly in the i-vtec rpms, more difficult than a short ram install, but well worth the power, went well with the magnaflow cat back system, without resinator! made the car more fun to drive, its a base with auto trans. so not a race car, but its fun for my gf. think ill get her some dc shorty headers, and skunk 2 intake manifold, trying to get it to beat my buddies rsx stock with a stick
