Please go beyond simple thinking to some science of it.
The throttle body controls the amount of air entering the engine at any given RPM.
'Under' the wide open throttle position, the throttle plate angle is the controlling factor.
The filter and the piping are already oversized for the size of the motor.
The intake is already piped from the outside.
The only change in power now does come from a change in air temperature drawn from the outside which you have no control over.
Lastly you cannot feel less than a 10 hp increase such that a change in intake hardware will not come close to that amount of power change.
Also as the temperature changes the amount of fuel injected changes and ignition timing may even change.
This come about from the Mass Air sensor, the intake air temperature sensor, and Oxygen sensors.
The thing that drives these notions of power and mileage increases are the old carbed cars that have no controls but fixed jetting and poor intake air systems.
This all goes by the wayside in modern day computer control.
Good luck.
