Save your money. The SpiralMax/Tornado twisted pop-can has been dyno tested (on the V6) at least to be worth nothing in terms of power and in fact may have produced a slight power drop.) Unfortunately, the tester's name escapes me at the moment but he was/is a pretty respected member of the Probe community.SPORTMX6 said:Has anyone tried this thing I saw on Tv called the Tornado Air Vortex? It inserts between the filter box and the throttle body and spins the air into the engine.They claim it increases hp. The physics is also kind of wild. Any feedback?
