The AEM 21-415P 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 Accord 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 relocated to the passenger-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine’s factory emissions control devices including the engine breather hose. 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 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.

Doug from Old Bridge, New Jersey
July 11, 2015 - Part 21-415P
I purchased this product, for my 2002 Honda Accord 2.3 (ULEV). I was looking for a little more out of my 4cyl, and this was the answer. Installation took about an hour, and it is highly recommended to purchase new Body/Splash Guard retainers BEFORE the installation begins (as the clips are old, plastic, and frail... making it damn near impossible to reuse them). After the instal, came the test ride (after letting the engine warm-up for about 10min). The moment I stepped on the throttle/gas, the difference in power/acceleration was obvious. The pick-up was 3x better, and the exhaust note changed slightly (I am still using the stock exhaust), not to mention how much more fun it was to drive when the V-Tech kicks in. As a precaution, I also bought the AEM 1-4000 Air Filter Wrap... as the air filter sits approximately 6-10in behind the Fog-Light receptacle on the bumper. This will help prevent water from entering the filter, and acts as a Primary filter for any type of dirt/road debris. I chose AEM for their product reputation, and I am so glad that I did.
