Product Details

Part Number: 21-506C
Brand: AEM Intakes
Color: Silver

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 and 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
Chad Solomon | December 3rd, 2013
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!
great product
Ryan Keyton | April 12th, 2012
wow this intake is amazing!. no hydrolocking. if your car is all stock you cant hear the vtec very well but with this mod it makes vtec scream. its a great first mod. in my opinion its the best out there. it has this awesome whistle while driving that could make people who dont know anything about cars think its turbod. stop searching and buy this. hands down flawless. A++
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.
