Cold Air Intake & Milage

[Cyn97]

Was just wondering if and what kind of MPG gains people have seen with an aftermarket intake. Obviously this will vary a little depending on brand etc... but I'm just looking for a rough idea.

I realize that many people with performace upgrades drive higher in the power band to see/feel the maximum benefit from the mod(s) and these people will likely not see any MPG gains as a result, but I'm talking just plain moderately conservative driving.

Sorry if this has been posted, I didn't see it in the search. Also posted here in the fuel economy based on the nature of the actual question, but mods, if you think this should be in the tech/performance forums, feel free to move.
