2. The location of the air cone is important (inside the bay v. outside the bay)....HOWEVER...it's position is NOT going to mean jack-squat if you disregard #1 above (what are the materials comprising the piping?). In the case of exterior bay located air cones, if the air kit uses CHROME PLATED pipes then they will not soak heat to warm the air intake air IF THE CHROME PLATED PIPING IS ON THE EXTERIOR OF THE BAY. However expect that that portion of CHROME PLATED PIPE that is running inside the engine bay to get hot and heat the air intake temperatures which can result in some temperature-gain offsetting of some temperature loss made from the exterior locatied portion of the intake-piping.
