There is no radiator duct.
There is a crash bar in front of the radiator and air just spills in from the intake.
Ducting air from a radiator intake duct all the way to the fender liner as an air curtain would be rather complicated as it would need to take quite a sharp bend twice.
In case of the smaller air intakes on the side, it's a pretty straight path, requiring only a small duct from the intakes and a small cutout in the fender liner.
Likely it would even work without the ducting and just cutouts, but not anywhere near as well.
I will take some pics soon, have to do some work there anyway.
