Installation is very easy. You can feel the difference in driving as the car feel smoother. I didn't notice much improvement in MPG, maybe 0.5 to 1 MPG.

Filter appears to be well made, fits well and installs very easily although instructions are poor. There is no arrow indicating air flow direction and in talking with a rep, the filter can be inserted with either side up/down as long as the "pull out" tab is in the front. Since installation was only a few days ago, it's too early to assess it's capability but, it will probably work fine.
