Had to readjust all 4 "clamps", so it took much longer than the 10 - 15 minutes some others are reporting, probably more like 45 minutes. Directions on how to change the clamp position could be more clear. Fits good. Have not had it on long enough to see if it improves gas mileage -- if it does, I would be happy with another 1 (or 2?) mpg.
