I had an AEM CAI on my Prelude and loved it. You could hear the whistle of air every time I got on it. Also it was located in the front lower fender, outside of the engine bay...hence CAI. This one for the Ridgeline is really a short ram intake. It is located inside the engine bay and realistically is not a true CAI. Also, from the instructions, it still "uses" the OEM intake box, there must not be any holes in the lower engine bay for a true CAI. They did report a gain on 13 HP on the Pilots dyno test though.
