That's only part of it. Like I said before:

Shorter intake lengths allow for more power. Period. That's how it's always been. Longer intake lengths can help build more torque, but the main reason CAI's make more power on the street is because the intake point is away from the higher underhood temperatures that a short ram can see. If you make provisions so that they aren't an issue, a short ram will make more power.
