After installing the filter in our Acura, we went on a 3500 mile trip. Which included crossing many mountain peaks at 9000 plus feet, endless miles of high desert and high plains roads. After coming back home, it was back to the normal everyday type of driving everyone is familiar with. Our every day type of driving gas milage. Went up an average 1 to 1.5 miles to the gallon. Our first cross country, have nothing to compare with but to give the results. Gas milage average 28, and got the high at 32. Seat of the pants performance,......could feel the difference in increased horse power. Even at altitude there was always more than enough power.
