I am trying to recover the MPG's I used to get out of my 1999 Expedition when it was a newer. I added Accel Ignition Coils, Pulstar Performance Plugs, Airaid Throttle body spacer, and a cold air intake system. The power with the combination I picked is outstanding. I have not been able to drive it enough to figure out if the MPG's have really gone up as this vehicle is not my day to day driver. I highly recommend the Accel Coils.
