Replace a Ferrite Inductor with Air Core Inductor Coil, equivalent or better upgrade?

Replace a Ferrite Inductor with Air Core Inductor Coil. When you replace a Ferrite Inductor with 0.62mH 18awg by one Air Core Inductor Coil, which value and awg will be equivalent or better upgrade for crossover board? I have same question for a Ferrite Inductor with 2.4mH 18awg by one Air Core Inductor Coil,which value and awg will be equivalent or better upgrade?

Replacing iron core Inductors with aur core ones shall reduce inductor saturations at higher frequencies. You can choose lower gauges (thick wires) as per your affordability as lower gauges shall be lower in resistances. Usually 14 awg is fine for woofers and midrange drivers.

How about tweeters: The original came with 0.23mH 20awg or maybe 22awg Air Core Inductor Coil and I am thing to replace with 0.25mh 18awg 22ohms or 0.30mh 18awg 24ohms. some people use one, others, the other one, I don't know which one will be better or correct upgrade..

You must stick to original inductor values. The gauge of Inductors you can change I.e u can use thicker gauge wires which have lesser resistance, it shall enhance sensitivity of speaker/tweeter within that circuit. Usually crossover is tuned with respective resistance of components in mind and changing this resistance values via using upgraded/downgraded components results in sensitivity changes. Better shall be to stick to original gauge of wires.
