Yeah Nice work.. I would love to do one of those things

 

You can find them in with the vinyl siding parts area at HD. It actually even comes with a block off flap but it restricted the airflow too much so I just cut that and the insides out of it with a Dremmel and painted it black (only come in white). Once you see the part it's pretty simple to figure out how to cut out the underside panel and mount it and all. I did cut out the piece of air damn right in front of it as well

 

Sorry I don't have any pics but mine looks and probably performs better than any I've seen here. I used a marine vent cover for a scoop painting it black. It's got a smooth curve on back side. Its really meant to be used topside on a boat as a cover for air vents but makes a great scoop. Look for one in a boating/marine supply store. I got this idea from searching the web back in '95.

Secondly, I boxed in my K&N FPIK filter by creating a trapiziodal box out of plastic panels, rtv and reinforcing rod. It's not easy create a box that fits the space and wraps the filter. I hinged and attached the scoop to the bottom side so that I can with three screws pull out the K&N for cleaning. This box causes the scoop to actually ram air.

Thirdly, I moved the IAT sensor from the elbow to my air box. This made a big SOP difference when accelarating in hot weather from a stop light.
