More dense air=more o2 in the combustion chamber so you get a little more power. Also the colder air will drop your intake temps down a decent amount. The difference it makes to my n/a car is it goes from a little chirp into 2nd to spinning into 2nd. On the turbo car it is just a beast because the faster you go the front mount just gets colder and colder.
also cuz the air is more dense means more fuel in the chamber so...idk if that matters.
