Who has built a cold air box?

I'm thinking about building a cold air box, partially to mount my power steering reservoir, partially to keep hot air out...

Its a small hole in the front clip, maybe make a bigger hole in the inner fender similar to what current vehicles do?

Air intake I have is a carbon fiber piece from Arrington Engines, I've been running it on my '09 Challenger SRT8 and looks like it will fit well on the Barracuda. Gotta trim 1/2-1" off to get more clearance for the filter or alter the inner fender.

So, who's done this?

Thanks,
Steve
