Its the same on our cars.
Not sure what is being refered to as air only being pulled from the headlights. I actually took my cutoff tool on my compressor and cut excess metal to make the fenderwell access larger to the wizaired box that mates up with it. So even if my headlight area isnt allowing much airflow, the dang hole to my fender will allow all the air it can suck. Hole is 3x the size of the filter.
I like the FWI because the airbox takes up so much room. I have thought of switching for appearance reasons only.

There are a few good options, and everyone is going to back what they believe. My advice take the info and make a choice based on what you think makes sense.
