I have been modifying my front lower valance several times, but I have the final solution for air intakes:
The two side intakes are for the two fender oil coolers, the middle intake is for front brake cooling, with ducting through the trunk. With the oil coolers, it's difficult to route the ducting from the two outer intakes, hence the middle one.
I might do a mold of the valance, and make a light weight FG or CF valance.
