More air flow equals better milage?
I saw an ad for an air intake today saying how it can improve gas milage. I thought with more air flow, the ecu would compensate by adding more fuel causing milage to go down, but horsepower to go up.
do they give you better or worse milage?
16: Q: How much will this intake improve my gas mileage?
A: A lot of companies will claim their intakes will increase your gas mileage by some inflated number but they really don’t know. By increasing the amount of air into your engine, your engine will be able to burn gas more efficiently and in turn crank out more horsepower and torque and therefore decreasing gas usage.

if the intake ACTUALLY increases air flow, then the engine should compensate by adding more fuel. sometimes, this creates enough power to keep the fuel mileage the same or MAYBE increase it, but id say about 90% of the time an intake will very slightly lower your mileage
it's a tuff debate. the reason is the control points. How far the throttle body is open and also the computer adjusting the fuel as it looks for the optimum a/f ratio. Different vehicles control in different ways.
If your driving 60 mph and the throttle was open 75% and now with the intake it only needs to be open 70%, what have you lost?
I don't know the real answer to the question. just that it's not an easy question.

breathing easier usually equals better mileage because you have to press the gas down less to do the same amount of work
my fox used to get about 24mpg with h/e/i and ran low 14s
since i turbocharged it i usually get about 28mpg highway and ive gotten 29.9 before... while running mid/low 7s in the 1/8
