Yes! It works. To start it has to be a 3.8. My 08 has a k&n cold air intake, superchip programmer set to 93 performance, and modified exhaust. The throttle body part number is 53032837ab and you can buy it new from mopar from $150-$175. It is bolt on and plug in and go no mods ant takes 5 minutes. It made a huge difference, especially on throttle response. You can see the difference

 

It is super easy, you over paid, and get real about it making a huge difference.

 

I did not say what I paid, cost is 129. And it did make a difference
