Hi folks. The lower valance on my full-size van hangs down about 6 inches. Instead of pushing air down, it scoops it up. I have a 2200 mile trip coming up and every bit helps. Do you think if I removed it, my fuel efficiency would improve? There's 16" of space behind the valance (measured to this metal plate under the front axle) if that makes any difference. Advice? The bumper does have some holes I could mount to if I were to home-make something to make the air flow go down and under.
