Brainstorming ideas for coolant crossover on Air-Gap intakes

BTW, copper and aluminum are not electrolytically compatible so you will get corrosion (even in dry CO) if you put them in contact. So I would be thinking stainless or aluminum for the tubing. If you air seal up the area, then the epoxy and tube idea may work out.

I still wonder why not just switch to the Performer intake and have it heated normally from underneath with the oil and get rid of the open air under the plenum.....
