Don't expect any gains from it. I bought cause I had money burning a hole in my pocket and I wanted the whistling noise. Still get the same mileage as before cant tell if there's any performance increase but it sounds good.

It was easy to install and it look good . I had better throttle response and better low end torque . I have k&n cai and dual exhaust . It goes with them just fine .

That whistle though.

So far so good. Not really great, but not horrible either. No change in gas mileage. Stronger take off from a stop. Love the whistle sound it makes. I'm sure it might bother some people, but i enjoy it. The whistle kind of makes the pickup sound a bit more aggressive. Decent bang for you buck.

Noticeable improvement in torque, MPG hard to tell. Overall easy install, quality part, cool addition. Can't hear whistle except at times due to dual exhaust. Would like to see it around the $80 mark though.

easy to install

I recently installed this throttle body spacer knowing there would be some type of whistle. I did not realize how loud it would be. It is a high pitched whistle that occurs the majority of the time when accelerating or traveling on interstate. When traveling over 55mph the whistle is constant and is still heard over the radio. It did give me a better throttle response, an additional 1mpg in town (only ran one tank so far) and I can feel a little more power off the start.

i put this on my 07 f150 5.4 liter that also has roush cold air intake and free flow exhaust the exhaust and cold air have been on for two years now and while some hp increase was felt not as much as the spacer. i could bark a tire before now i have enough low end torque to actually spin a tire. ive had to relearn mt throttle. i have not heard the whistle so many people talk about,i guess the exhaust drowns it out. so do it dont waste any more time.
