Fairly easy to install in my 11 Nissan Frontier Pro-4X, except you need to loosen things up and twist the filter into place before tightening down as the directions state. Feels like a bit more horsepower and the sound is nice. The directions state to disconnect the black battery terminal. I did this to be on the safe side, but it resets your mileage computer so it is hard to assess any change in mpg's. I'm happy with it and hope it helps offset the mpg reduction of the larger tires I installed.
