PV=nRT... Pressure * volume = (constant) number of air molecules * Temp

to keep P the same, (R of course stays the same) when T drops, V has to drop to match it.

basically it is done that way to try to reduce boost drop due to the cooling of the IC. the air on the cold side is more dense, so it takes up less space. you need a smaller pipe to maintain the same velocity. you want to maintain the same velocity to maintain the same pressure.

/physics lesson.

+1 to you sir. There is also a velocity concern (mass flow rate=rho*V*A=const in a closed system) but intake velocity is not as important to most people building FI cars so it's often overlooked.
