Does anybody know where to get one that will fit, or maybe some tips on how to create your own??

 

Well there is the cold air box? If that's similar to what you mean.

is that just a aluminum box that goes around the filter?

 

the answer is yes

 

sheet metal and rivits or a welder or if you want to do a good one use sheats of plastic and a epoxy to hold them together and then make a box around the fliter and cut a big hole in your hood yeah or well maybe not the hole but the box out of plastic would be cool it would not absorbe as mutch heat
