bOUGHT MY Throttle body spacer last week. works great. love the whistle and makes my flowmaster sound better. not shure how much power it has given me. but there is definatly a small noticeable increace in power. pretty easy to install. recommended

...I'm enjoying my purchase and still consider it worth it if you have other mods for this part to work with. I do not notice much of a difference in power although it helps my car's engine to run smoother
