wow.
this has to be some of the worst BS i've ever seen.

the stock intake is designed to keep the airflow quiet.
it does this with all sorts of non-smooth surfaces inside. this creates turbulent, slow airflow.

a CAI does 2 things.
1. it brings in air from a cooler area in the engine bay (or outside of the engine bay). this cold air is capable of making more power (cold air is denser, more o2 in the air getting into the engine, more power)
2. aftermarket intakes aren't designed to be quiet. they use the smoothest surfaces/tubing to get the highest velocity, smoothest airflow into the engine.

so there's your reasoning.

as for what's been posted above me, i'm not sure where that information came from, but if you don't really know, don't post a lie...

cool the motor fluids? and how does it do that.
pointless mod on a stock car? riiiight. a mod that makes power is pointless?
