Best Dry filter intake around

Contrary to what a lot of people think, in 99% of cases you will experience no additional power/mpg with this mod unless you have additional supporting modifications and/or a re-tune of your ECU. In my case, my intake was the largest restriction so it did help marginally, but mostly helped to aid in reduced intake temperatures for continuous power delivery over time. For my 08 Accord V6, the install was a lot more complicated then I expected, but this is NOT AEM's fault of course.

It sounds like a BEAST!

The auto anything price was the best. Trust me when I say that I have been doing a lot of research before I bought this CAI but I don't regret it. My car doesn't lag either now it able to breath freely. Installation was easy, but what was so tedious was taking out the OEM parts.

Great Product !

I bought this product for my 2008 Accord Coupe V6. It produces a great intake sound at the RPM where VTEC kicks in. At 5k-6k RPM it sound vicious without sounding the least bit "ricy". At normal RPMs and in normal driving through city traffic the change is barely noticeable. The estimated change in HP by the manufacturer is 7HP, which is a little too small to be noticed by most people unless you had some recorded times before and after. However, one thing I did notice was a 2 MPG improvement in fuel economy in my daily routine of mixed city/interstate driving. The only negative thing is this product isn't for novice installers. It's not an advanced install, but it's something that was made greatly easier with the use of a hydraulic lift. The directions assume your using a wheel jack, and require you to take off a few extra parts not needed if using a lift. The product fit perfectly and had all required parts for the install. The filter sits right behind the driver side fog light and in a very well splash protected area in the bumper.
