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.

This was easy to instal and you can see a difference if you drive a car that reads your miles per gallon, it did boost me up about 3 miles to the gallon. I didn't feel much of a power change but i do hear the whistle like a turbine once in a while depending how your gears change. I definitely would had not paid more than $30 for the other ones since you cant tell the difference dramatically but worth $30 for sure to instal as easy as it was.

THIS THROTTLE BODY SPACER IS A NICE ADD-ON TO MY AIRAID COLD AIR INTAKE I ALREADY HAD ON MY 07 JEEP GRAND CHEROKEE 3.7L V6. EASY TO INSTALL, GOOD QUALITY AND INSTRUCTIONS. FEELS LIKE THERE IS A LITTLE MORE POWER AT LOW SPEEDS. I DON'T NOTICE THE WHISTLING SOUND THAT I HAD READ THERE MAY BE. IT ACTUALLY SOUNDS AND SEEMS TO DRIVE SMOOTHER TO ME. I THINK IT WAS A GOOD INVESTMENT.
