This ^ is why I thought it may have to do mostly with engineering an appeal to the masses with an ultra quiet yet powerful/efficient engine. As many have reported, the CAI produces a noticeable change in engine noise, which is undesirable to the soccer mom, yet exciting to the enthusiast. Just curious what others thought about the subject.
