While I'm not sure how much my mileage has increased, I've had 3 upgrades in the same week with new ones Tires installed, the cooling air intake and edge tuners. Together they increased my highway mileage on my 2006 Chevy Silverado 2500HD from 11 mpg highway to about 18 mpg. Installation was easy and over time even a 1mpg increase for this upgrade would have paid for itself.
