I'm intrigued by the idea...$100 isn't much to spend for even a 5-10% fuel savings, and they claim around twice that. I don't want/need more power (the '09S has plenty), but I'm always interested in saving fuel.
Just wondering if anyone's tried one of these on any vehicle, and what sort of real results might be expected... Thanks!
