The AFE cold air intake was easy to install if you are mechanically inclined. If not, you might have a little trouble as directions are not great. Adequate, but not great. The horsepower gain was immediate, as well as the throttle response. Torque and mileage have improved too. Overall I am very satisfied with my purchase.
