Immediate increase in mpg from 10.5 to 13.2. Very pleased to see an impact so quickly.

Switch out stock filter for the aFe pro-dry S air filters in my 370z. After two months of use I have notices a 1.1 more MPG so I am very happy with that. I also feel like the car shifts smoother through the gears.
