Hehe...If you could find a way to make them a little more efficient you might line an intercooler with them or an intake. I have a working model in my garage right now. Problem is they consume massive amounts of power and give off MASSIVE amounts of heat. And they dont stand up to alot of CFM. Right now I might be able to get a 3-4 degree drop in intake temps...not nearly enough to market...but then again...these kids today will buy anything.
