Where can I get more information on the Tornado? If it would get me 2MPG better then what it is that would be helpful. I also saw on Ebay a filter like the K&N but different brand, has anyone used that before?

I was also wondering if anyone knows were the fuel cutoff is at? I can't get the Kia started and I see they have a fuel cutoff. I know on the Ford's its down by the pass. feet, but I looked there and didn't find anything.
I'll check with the dealer tomorrow if someone can't help me yet today.
