throttle body spacer

[deke rivers]

I have a 04 tj and was wondering if anyone out there is using a throttle body spacer.. im wondering if it might improve mileage...I realize that the shape of our jeeps aren't built for great mileage but willing to try anything for any increase..thanks...

I had an 04 TJ for 9 years and ran a throttle body spacer for probably 5 of those years. Zero change in mileage but it had a nice whistle at times. :roll: I figured, it may or may not help but it can't hurt.
