Forgetting about the unproven facts behind the "tornado" wouldn't the simple fact that no automaker has bought the rights or developed a similar concept for their OEM intakes make the idea hogwash? With hybrids selling like hotcakes and small car ad's bragging about how there vehicle gets "x mpg's more then..." it would make little sense why they would not incorporate this "tornado" concept into there vehicles intakes since this product has been out for a while now...
