Looking at the underside of my engine compartment, I don't have much room to work with. The front bumper to the radiator is my largest gap, and a partial belly pan from there to behind the radiator takes me almost to the oil pan. Good news is my radiator is fully enclosed in a shroud, so ducting the exhaust air from the fan should be only a minor challenge. I think I will use the stock valence piece to make a template for whatever material will be the front pan.
This morning was more duct taping and thinking about what I am doing more thoroughly, time to see how it does for the morning commute!
Ambient temp is ~70*F with wind @20-30mph from the South (strong headwind)


Have a wonderful morning!
