This Really Helped with the MPG on the Highway, But I really didn't feel any gain in HP. It got about 3 more MPG than before.

i installed this throttle spacer in about 15 min. very easy. i already have a k&n air intake installed, so with this added, there is a definate notice in a power gain. gas milage has improved about 3 mpg. the only downside to this product is the whistle it produces, other that, its great.

Serves it's purpose. I am getting about 1 mile better around town, and 3 miles better per gallon on the freeway. This product coupled with CAI, and a less restrictive muffler really have improved the fuel economy on my FJ, while also increasing HP and torque. As far as throttle response I noticed minimal increase, but any increase is good for paying $30.00. Install took about 15 mins. Cheers!
