Something i thought of, and put on my Twitter page, that i think is legal, a pipe that injests cold air, gets heated by getting close to the engine, and then goes into the EBD zone. You could have the pipe exit a 45mm diamater and the inlet a 70mm diamater so the air speeds up a little as well, however it could be a slightly draggy concept as well. However it would work.
