Does anyone know of a design template for an cold air intake airbox? The template may or may not work with my filter, but that's what I want to find out. I was thinking of making it out of sheet metal, which I already have.

 

Look here in out tech facts section https://www.dieseltruckresource.com/...n&onlynewfaq=1

 

Thank you. I haven't been able to get those tech files to download, but it is titled as a heat shield. I want a completely closed box like the stock airbox.
