Here's my theory, and I'm stickin to it.
-The stock air intake pulls from warm-hot air of the engine compartment.
-The CAI's function is to pull in colder air from outside the engine compartment.
-The cold air has more mass (more oxygen molecules).
-When the fuel injection system's Mass Air Flow sensor finds it has more oxygen available, the injection system can meter in more fuel.
-More oxygen plus more fuel equals more horsepower.
To make an efficient path for the cold air, a well designed intake moves the air through the most direct route, across a low-restriction air filter, through a larger diameter pipe. Like a big bassoon, this must be what makes my TRD CAI go VROOM-VROOM when I press the pedal hard.
Woops- Gotta Go!. I hear sleigh bell outside. . . . Must be Santa!

dense cold air = richer mixture of air/fuel ratio = more hp
