Looks like they used a strip of cardboard fiberglassed in but I want something a little stiffer. Heres a picture of the underside. I was thinking about adding the aluminum strips about 2-3 inches in from the edges and then making the entire hood a little thicker with an extra couple layers of mat. I'm going to take out the plexiglass that partially covers the scoop hole but I might add something simmilar cut to fit my air cleaner, seems like a good idea to really force the air in. So what do you think?
