This is a discussion on AEM vs. Cobb intake system questions within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; id guess a tiny bit. i think zach has one....

^^ Exactly that...
If you get to the point where hydrolock is a serious concern, you're an idiot and you deserve it.

Guy the box is really pointless on turboed cars because of the fact the by the time it reaches the turbo it's already hot. Boxes are more used in n/a cars. It's nice to have to use with stock duct but other then that it's not necessary
Wrong

OK OK, instead of just saying stuff randomly, as you, EUROWRX22, are doing, let us take a logical look at this.
PV=nRT, where P=pressure, V=volume, n=# of moles of gas, R=gas constant (related to Boltzmann's constant, in which energy at the particle level is related to temperature), and T=temperature.
So, as T decreases, assuming n is constant and, of course, R is a constant), what must happen to PV? Well, it has to increase if T is decreasing. What does this mean to your car? Well, as the temperature is decreasing, your able to jam more oxygen into your compression phase (as T rises, the density of the gas decreases due to density = m/V => V = m/density, and thus P(M/density) = nRT). Conversely, as your temperature increases, your turbine wheel must do MORE work (i.e. spin faster) to compensate for the decreasing amount of oxygen, which, at some point, will be unable to spin fast enough to keep up and your power will decrease.
Where is some good proof? Here is a MS6, same tune, same exact setup, same DAY, with a 20 degree intake temperature change.
It is clear to see that intake temperatures DO matter to overall power production in a turbocharged engine.
