I am not sure but based on Bf-109F-2_06.jpg that 109F's boundary layer seperator ducting is missing from the 3D model.
This was present on the 109F (deleted on 109G) and was a seperate ducting that picted up the boundary layer at the radiator inlet and passed it through above the radiator without disrupting the flow (and thus reducing radiator drag and increasing its effiency)
