the reason the original airbox is colder than any other pod filter you can mount is because the airbox essentially sucks fresh air and not heated engine room air.
It will get hot when the car is stationary in traffic but will cool down quickly as soon as the car moves.
The pod/cones get blazing hot and move stale air in the engine room, they also have giant holes in them which cause rapid wear of the engine as those huge holes pass dirt/sand/debris in the engine.
