The answer is basically (and it is much nicer when you aren't yelling) that
higher flow filters won't improve your mileage at all. They _can_ improve
your performance with the throttle wide open IF the airflow is the limiting
factor (which it is not on a stock vehicle). If you have done other things
to increase engine horsepower (and that includes a high flow exhaust system
and modified firmware at the very least), it's possible to get into a
situation where airflow limits you at maximum throttle and a high flow air
filter system can help a bit.
A lot of the high flow systems get their flow rate at the expense of
reduced filter efficiency. That's fine for a racing car, but it's really
bad news if you ever drive on dirt roads.
In the old days of carbs and manual chokes, airflow was a big deal because
changes in airflow would translate into changes in fuel mixture. These
days with modern fuel injection systems it becomes a big issue only at
high RPMs because the fuel injection system keeps the mixture correct. If
the filter clogs up a little, you have to press the pedal down a bit more
to get the same power, but the mixture is precisely the same as if your
filter was not restricting anything, because it's a closed-loop system now.
