How does a cold air intake work?

Answer:
Instead of drawing the air from your engine bay, a cold air moves the air intake point to the lower front of the vehicle away from the engine bay, thus exposing it to colder denser air (since hot air rises) and taking advantage of the forward motion of the vehicle to ram air into the intake.
