This was easy to instal and you can see a difference if you drive a car that reads your miles per gallon, it did boost me up about 3 miles to the gallon. I didn't feel much of a power change but i do hear the whistle like a turbine once in a while depending how your gears change. I definitely would had not paid more than $30 for the other ones since you cant tell the difference dramatically but worth $30 for sure to instal as easy as it was.
