Cold air intake methods

The engine is a Toyota 4age and the elbow is the stock hose just turned 180* to fit under the bonnet. The air box inlet opening is 2 1/2 times the area of the TB. I have a hole in the base to drain any water out, but luckly I have never tested it in heavy rain.

I would think that most Seven rads would be slightly smaller then then one I have installed which would make the fabrication of the air box a little easier when fitting it above the rad. The box is made from one 1/8" thick fiberglass panel that mounts to the actual TB, and the bottom and sides are 1/16" thick fiber glass. The 1/16" glass is flexible so you can bend it to the curved shape. I then just used aluminum right angle pieces and roughly riveted the shape together and the layed glass up in the corners and seams. Probably 4 or 5 hours to fab the thing.
