there's one born everyday......... C'mon do you really think the Porsche engineers left 20 hp out of their engines by not using the right intake plenum? A non-moving static piece that would cost hardly anything to mass produce? Check out how much the factory power packages cost, about 20 grand I think to get like 40 hp. They have to make all kinds of internal mods to get there, not just bolt on a few 'trick' pieces. The factory has been doing this awhile, I think if it were possible to get 20 hp that easy, any car manufacturer would do it. As for guys who claim it works, I'm skeptical. Even in medicine placebos work about 20% of the time for all kinds of results; pain relief, nausea, improved joint motion, increased breath volume, etc
