Review on AEM 21 407B Blue Intake System by Charles Osguthorpe

This thing really performs at least as expected. Never put your car on a dyno so you don't know how big the win is. The last thing it gives you is an acceleration noise as you take off and you can hear the air intake sucking in air. The installation took a while, as expected from Honda, but it fits well. Use an angle grinder with a cut-off wheel to cut a hole in the fender well. It makes life so much easier and cuts anything in less than 5 minutes with no issues.
