Not a bad idea with the air scoop.
I did a similar mod on my old Ford Probe. (horrid 16v version though!)
I bought some tumble dryer ducting and a right angle section which had a round part at the top for the ducting to clamp onto, and a rectangular 'scoop' on the other from Focus.
I poked the 'scoop' out the bottom of the under tray, and had the ducting to right up into the airbox through a drilled hole.
It worked really well, especially when at speed, classic bit of Ram-Air effect collecting that cold air from under the car.
The only drawback would have been if I went through any deep puddles, and it would have scooped up the water a treat, but I doubt it would have the force to go up the whole length of ducting and into the airbox.
