My Jeep gas mileage has increased from 15 mpg to 17 mpg on first tank of fuel running A/C and I am sure by not running air in the winter it will do a little better, Thanks K&N,

I recommend this air filter to anyone with a 2001 Jeep with a 4.0. Had a noticeable increase of power as soon as it was installed
