This increased my MPG by about 10 MPG or so. I used to be 46 and now I'm 55-60. I also have other mods for my car that allow me to get the most out of my small diesel engine. The only thing that takes some getting used to is the sound, you can hear all the air just being forced into the engine. While that's good, I notice that my engine revs less when I accelerate slowly. It also increased my throttle response.
