I do notice a difference at higher RPM's and so far I have seemed to get a slight increase in MPG so far based off avg. speeds and my MPG. Too early though to confirm that but so far so good.
It's impossible to get better mpg from a filter.
If you are talking forced induction, you may be right. Or if you are talking about an intake system where the filter accounts for div>
The only way this can happen is on an old carbureted car, with the restriction causing it to go rich. On an injected car, AF stays the same no matter what thanks to the 02 sensor.
If the filter restricts airflow, the car makes less power, it doesn't affect mileage. If the filter caused it to get bad gas mileage, imagine what a partially closed throttlebody would do to mileage.
Not quite. I'll let you figure it out. Just remember, you need to control both air flow and fuel flow to maintain a proper Fuel:air ratio AND proper power production. If you limit just one, you can only regulate fuel:air ratio OR power production, but not both.
