yes kind of
a better panel like k&n lets more air and they also mess with the sampled part that flows through the maf
Ideally a flow inside the intake tube where the maf is is a laminar flow with no turbulebce but in reality it is not but stock airbox is very good at keeping turbulence at minimum
they mess with the scaling usually making everywhere leaner, so the leaner it gets the more power it gives because stock tune is too rich
this is quite different with restyling cars as the tune most of the time is in closed loop and a lot leaner .. but after 6400 rpm and also when exhaust temp gets very hot it turns back to "old" settings like pre restyling cars' tunes
if you can t tune it ur best bet is just a filter panel like your friend
