You've seen them for sale on the Speed channel, and now Dali Racing has a link to one for the NSX. It's the metal (stainless steel?) "Tornado" insert device with fins that channels air flow into a vortex when you put it into your intake. They claim up to 10% increases in HP and modest increases in fuel economy. Anyone using this in your NSX yet? Reviews?
