not that its relevant to this post but thats incorrect in theory i understand what your saying but its incorrect. the reason a cai gets you more power is that colder air has a lower enthalpy value at roughly 80 degrees airs enthalpy is about 128 btu/lbm and at 110 degrees its 135btu/lbm. So that being said a cai will easily drop your intake temp 30 degrees there by dropping your entropy 7btu/lbm because its easier to compress a colder working fluid.
since gas millage and performance are both offshoots from efficiency the more efficient your engine the more power potential and more fuel efficiency. just depends on how heavy your right foot becomes, but if you put a true cold air on ANY car and drive the exact same youll see at least 1+mpg increase trust me ive put intakes on 5 different cars this month all same results.
hope im not coming across as a
or anything im an energy sys engineering student so this stuff is my life lol
