It always amazes me when someones says they get 1 mpg better with something. I mean, is that really measureable? Ambient air temp changes from 1 day to the next, foot is a little heavier, got a different brand of fuel etc.... When someone makes a claim like that, I have to ask if the conditions were controlled or not and what were the variables.

I didnt buy my CAI for better MPG but I was trying to provide the original poster my impression. I drive the exact same roads to work every day 5-6 days a week. I had the car stock for 6 months and average around 18.5MPG regularly, ie 50+ tanks of gas. I put the CAI and Tune on and running the 87perf tune I get 20.5MPG regulary ie 20+ tanks of gas. The rest of the time I switch between 93 Race and 93 torque just for fun and it really fluctuates but no matter how I drive I have never gotten worse than 18MPG for a whole tank. City driving I can watch the MPG drop quickly and on the highway I can see it climb quickly, much more than stock.
Personally I am happy with anything above 12MPG that I got out of my last mustang.
I recommend the lightening and free mechanical losses because that would also improve MPG but even better power.
But hey I am not comsumer reports I am only letting you know what I see with this mod.
