I have a 98 Ford Exedition with 9" of lift and 37" tires. I have done several things to it to include the Fram Boost Cool Air Intake, Edge Performance Chip, Flowmaster Exhaust, and much more... When I put the Airaid throttle body spacer on I really noticed a difference in the mid-range power and yes I have noticed an increase in mileage. And with 37" tires any increase in mileage is great!!! The sound the whistle makes isn't as loud or as annoying as I thought it was going to be. I kinda wish it was a little louder whistle. But awesome product. Highly recommended!!!
