It's like the Tornado. You might pick up a little HP and better gas mileage its up to you. On the Tornado commercial they showed a car pick up 10 HP on the dyno. All that little bit adds up......just dont tell anybody your running one. IMO I say pass it up and spend the 70 bucks on something better. I know a guy in a Focus who loves his Tornado he's always talking about. He said he felt an improvement.
