As far as CAI compared to SRi, a cold air will get you slightly better mpg and maybe a extra 1hp.. but it takes longer for the air to get to the engine, where as a sri normally has a purr at lower rpms, but loses its benefits after 15minutes.

* i have a 3' cold air that comes in 2 pipes, works great, i can make i either a sri or cai, but i always romp it for the noise, gain maybe 3-5hp? but no benefits as far as gas

* also have a 2.25' sri made by AEM, its quieter and matchs the stock dimensions, so i have increased my mpg even if im WOT.

IMHO, changing ur intake is the easiest thing to do, but the main reason to do so is for the noise, and if u increase your intake size, then you will want to match ur exhaust size, and going more then a .25' up or dow will result normally in a loss of power

If you are somehow able to increase the flow into the engine for any given throttle position (something that aftermarket intakes are only marginally capabable of doing), then the ECU simply adds more fuel to keep the air to fuel ratio set properly.

With the above said, "cold air" as in truely cold air, like below 40 °F, will inhibit fuel atomization and actually reduce fuel economy.
