This is my new 2008 Black Jeep Libby 4X4. And yes, after my Borla exhaust, CAI, and Lineage motor sport ground kit I went from 15mpg in the city to 17mpg. I don't know my exact hp gains, but can feel the definite gains in hp and torque, and can feel a difference.

Made my own cross bars, saved $200, and the look much better than the ones you get from the dealer or after market.
