Airbox turned out great!
I made this airbox for my '91 N/A out of aircraft aluminum and rivets. The lid is the same material with an aluminum piano hinge to allow it to pivot up and down. I made it so the snorkel will, theoretically, flow coller air into the enclosure while I'm in motion. Opinions?

Wow.. that looks really good.
If you decide to sell them, let me know, I'd be interested in buying one, especially if it included a good intake pipe and an apexi cone filter.

Actually, the perceivable performance increase happened when I changed to the cone filter. I didn't really expect another increase with the introduction of the box. I'm thinking more along the lines of engine longevity. I figure keeping the hot air form the intake helps. It's a revised version of my brother's design. He has a '90 GTU that's totally tweaked and he made the first iteration. He made me a copied set of his templates and I modified them to make a box with fewer seams and have a generally better appearance. Plus I like an actual lid instead of trying to seal it against the hood underside.
Sorry, guys. There are no production plans, but I can tell you it is not as difficult as it may look. The best template material is thin cardboard like a 12-pack box. Just get out there with a marker, some scissors, some tape and and a ruler and create a model of the box. Then take it out, lay it flat on your aluminum and cut it out. I used a nibbler tool I got from Radio Shack for $10. If you use thinner material, you may be able to use aviation shears. Then bend, rivet, file and fit in the aluminum. Piece 'o cake! Check out www.airpartsinc.com for beautiful, well-priced aluminum and piano hinges. Total cost for my airbox was about $40.

That airbox looks great man and I like the hinged lid better than sealing it to the hood too. Makes me want to stop being lazy and go out and make one for my car too!

That looks sooooooooooooo nice. I was just outside this morning around 10am trying to make one myself but um, well things didnt turn out so well and all I ended up with was quite a few cuts on my hand
Damn, you've just inspired me to go get some aluminum and make my own

I thought you all might like it. Thanks for the compliments.
Rxmfn, the aluminum just has a high reflectivity...that's why it may look transparent. There isn't such a thing as transparent aluminum. You may want to reconsider the use of plexiglass for a project like this. The heat under the hood will make it soft and fragile and it's VERY hard to work with in terms of bends, joints and curves. The beauty of aluminum is it is very easy to work with, it's lightweight and it's metal so heat isn't so much of a factor. I know what you mean about a hot box. I figure the cooler air coming from the stock intake snorkel (on top of the fan shroud) creates a desirable temperature difference. I've been thinking of some sort of insulation method, but again, underhood temperatures are killing my ideas.

thats one hell of a box. i have a turbo though, and i need to make an air box. but because its on a different angle, i couldnt make a square box, so it a lot harder, but i'll figure something out im sure
