Nice work!
Based on your wheel skirt photos, if I try it I think I'll make the skirts longer by maybe 8-10 inches, so the bottom forward corner ends up further forward. Then maybe the skirts leading corner can hug the molding and the body there.
I did a WAI. There's no tube in mine; it sucks in air heated by the rad and whatever heat comes over from the exhaust system. ScanGauge shows the intake temps are about 30 deg. F above ambient outside temps. Same filter box as on your car.
