Yes. In the proper application, vortexes, boundary layers, laminar flow, &c are an important part of what a VS does. But just sticking one on the end of an intake will more than likely not have any appreciable effect, positive or negative - as Jordo! has shown (at least for his setup).

I could be wrong (my personal experience with VSs is, for all intents and purposes, nil but I have a lot of experience with gas/fluid flow measurement), but everything I've read on VSs says they are an important part of tuning the intake system. If I'm wrong, please show me the light - I'm not too old to learn something new.
