For those that want to DIY powedercoat your intake runners and plenum I found a toaster oven big enough for the job. Of course I had to be that weird guy walking into Walmart with car parts in a ziplock bag, but it was worth it.
They are out of stock at Walmart.com and the store i went to only had a few left.

Only $50! This is the largest 110V toaster oven I could find. A 1.7 plenum will fit no problem, the 2.0 plenum might need to be proped up somehow. I haven't tried it yet.
