Lets think about this ..

Cold Air combust better than hot giving you a stronger combustion Correct?...Correct
So no mater the application wether it's N/A or Turbo/Supercharger, giving your engine colder air is always better than hot air.

short ram and cold air tubes will both heat up the same in the engine compartment, but where the short ram will start to suck hot air once the engine copartment heats up, the cold air is always sucking colder air. IE making more power.
