http://www.autostreak.com/tornado/ That is one of many sites that have info on it. I also have the K&N drop in filter made the motor run a little more smooth and noticed a little bit of a snappier response in the gas pedal. I put the filter in after the tornado gave me another mile per gallon a total of 3.5 mpg. All cars are different though remember some may respond better some worse just giving my two cents from what I have done on my sportage.
