if a wind blow too much on it , yeah that will cool down the heated wire which send a signal that is received by the ECU then adjust the AFR.
depending on the intake bent and location of the MAF sensor, yeah it might not be good at certain occasion.

+1. The MAF measures, as its name implies, mass flow, not velocity or volume. As long as you are within the operating range of the sensor, pressure and velocity at the sensor are not important. If you increase the system pressure (eg, ram air) the velocity will actually decrease to get the same mass of air into the engine (the air is more dense so it takes less volume to get the same mass).
Sensor location can make a difference due to turbulence.
The setup in the OP is not a ram air but an "enhanced" CAI. For it to be a true ram air, it would have to have the filters enclosed and sealed within the new duct work.
