Yes most CAI do add mileage, along with HP being the HP is more than you though it would give you (on the crossfire) your foot makes your mileage go to away every time you drive the car the mileage goes down, i am getting 9 mpg this is not a joke 9 miles per gal,,,now if my wife drives my crossfire she gets 20 in town and 25 on the road. I get 9 it doesn't matter if i am on a city street, a highway or the track i get 9 mpg. jim
