As far as the heat from the passenger intake: the temputure of the engine has stayed the same as before and after the mod. I am not positive that at 60 mph the original design was able to withdraw heat unless there was some sort of pressure drop because of the design. So in other words I have noticed anything detrimental while these have been installed. They are purely cosmetic.
DJ,
Do you have a sound file or movie of your cutouts open??
