Custom Ram Air Box Fabrication - Ram Air II Hood - See Pics
Well, I wanted to have the same option as the 98-02 F-Body, so I built my own air box based on the Volant CAI package - which is not an option for our cars. It wasn't a bolt-on seeing that I had to due a little bit of adjusting, and replace a few parts to get it to fit.
However, when it was all said and done.....I think it came out pretty good. It looks clean and simple, and so far those who have seen it in person thought it looked like a purchased factory product.
Anyone ever done something like this? If so, show me some pics of your setup.......I'm always looking for new ideas.
Here is the 98-02 intake by Volant...

Here's my custom box......

That's pretty cool! How much did all that cost and how did you do it? What parts and how long did it take you? I'm looking to do something like that on mine.

It took about two weeks and quite a few cuts and mistakes to get it right.........it wasn't hard, just tedious.
lol Anyways.......I'm wanting to do a summer project with my sons and build about 10 of these and sell them to members here.......gonna look into the total pricing. I'll keep you posted.

Yes, he's right it's just 5 wires. I didn't have to cut them, I just re-routed them to run down the inside of my valve covers.
Thanks for the compliment man.

That is wicked cool.
I wonder how hard it would be to fabricate a box out of fiberglass.. I need to find a way to draw air fro my ram-air 1 hood into my supercharger.

Re: Custom Ram Air Box Fabrication - Ram Air II Hood - See Pics
It would be ridiculously easy. Shape the box with cardboard and tape. Then fiberglass it. Attach foam or weatherstripping.
