    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. 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.

    Good but could be better

    I bought this to replace my injen shirt ram because I was tired of the heat soak. I have used AEM in the past and have always been pleased. Over all I am pleased with this intake. It was a good performance gain over the short ram. The only issue I have with the system is the replace my washer bottle would not fit correctly. I ended up ordering the Injen replacement bottle and it fit perfectly. I think AEM could spend some more time on design other than that it's a great intake!

    Take off your front bumper

    This intake kit has some issues when installing. The front bumper cover needs to come off, it's very easy. Windshield washer reservoir design is not the best. The bolt spacing on the reservoir is very tight. The fill tube does not line up correctly. The pumps are not in the stock location. The Injen reservoir appears to be a better design. This intake is dark gray not the silver that CRSX indicates which makes me happy. The best two best things about the intake are the sound and the CARB sticker.

    Great Intake!

    This is a great intake, arrived fast and was pretty simple to install. As expected had a little troubel with the washer bottle replacement, the power harness for the pumps ended up being too short to reach the connectors on the replacement bottle. The sound is amazing, and sounds especially mean after the vtech kicks in. Great performance increase on my 05 type-s, with no other mods (yet). Considerable improvement in power all accross the rpm range. Definitely recomending this product for everyone, but especially for a first mod.

    RSX Type S AEM CAI

    Very good intake system. Would recomend to all for the best invetment for significant gain. Installation is a little tricky. had a little problem with the washer bottle because the stock 10mm bolts are too small for these washer bottle so be prepared to have some long bold to secure these in place. The intake sounds mean and the VTEC does sound nice. Did make a big difference on my 2003 Supercharged RSX Type S

    Good CAI

    I picked up an an older version of this intake which comes with a relocater kit for the stock washer bottle. Fitment is great, just make sure you follow the directions closely and check that it clears the gearbox in all gears before putting everything back together (learned this the heard way). Requires cutting some of the splash guard as well which isn't too difficult. Everything fit and built quality was A+ in the kit I got. Would definately recommend.

    Not Satisfied

    I purchased the AEM intake with the impression they made a high quality intake. The first problem I encountered during installation was the stud broke of the insulator mount with light torque applied by a short open end wrench. The second problem I encountered was the mounting holes in the washer bottle were not far enought apart. Thinking the mounts were solid I tried to file one of them into a slot. Mistake! I filed thru and made a hole in it. I expoxied the hole shut then had problems getting the fill spout to line up. I had to rig the mounting with spacers to get it to install correctly. Overall I had the bottle in and out 3 times and the intake is mounted in place with zip ties until I can get a resolution on the mounting.

    I haven't really seen a difference because I recently put my AEM COLD AIR INTAKE (RED) in with an HKS EXHAUST SYSTEM(highly recommended best performance catback system) but the AEM looks nice hidden inside the front of my car and hopefully will keep my engine cool for a long time. Good equipment though.
