Exactly - the only time there's any possible difference would be WOT if the filter was restricting things.I'm saying this tongue in cheek. Because you know this is true.
But to the OP. There is actually a HUUUUGGEEE restriction in the intake most of the time you are driving around. Its the throttle plate. The throttle blocks 95% of the intake at idle and opens more as you press on the gas pedal.
Either way, you are intentionally blocking the intake to control the engine. The engine meters fuel based on the "manifold absolute pressure". It doesn't matter whether a given MAP is achieved with a poor flowing air filter and a slightly more open throttle or a perfectly flowing filter and a slightly more closed throttle.
Bottom line is that any kind of intake will have ZERO impact on fuel economy.
The filter isn't restrictive at highway speeds - the throttle plate is.
And the PCM adjusts things accordingly.
I have to laugh at the YT videos 'proving' this and that - a one time test.
Marketing - like the crap "powermaster" alternators sold to unsuspecting 69 Camaro or 70 AMX owners believing that a 200 amp alternator will help them.
CAI - a solution looking for a problem.
