Looks great! The white bumper really looks great. I wanted a white truck but they didn't have one in stock so I took a black mostly because the bumpers and grille and everything already match and don't need painting. But the dumbest thing is the undercoat is white so if I get a scratch it sticks out like a sore thumb! Who ever heard of OEM white undercoat?
Let us know if the cap helps fuel economy. I don't particualrly trust that mythbusters air bubble thing.
Did you ever figure out what gains you got from the air dam?
I just installed a salvaged Bronco II rear swaybar
and replaced the knobby tires with 215/75/15 Michelin Radial X.
