On what vehicle?
I read that on the 4.o they do a little.
I had one on a 99 3.9 mag and it didnt do shit, even with high flow cat high flow chambered muffler cold air intake and doctored up jet pcm. Spacer was last to go in and it literally did nothing.

i have had expirience with them on chevy's. on my blazer i went from 20 to 22mpg. when i worked at the gm garage we put them on fullsize trucks all the time, customers saw 2mpg better economy on average. the cheap trans dapt spacers are cool cause there isn't that annoying whistle. but on the downside, then you can't tell your friends you have a supercharger.

If you run a motor that lives in the higher rpms, increasing the velocity of the incoming air with a spacer and a larger TB will have a better effect than on a motor that relies more on lower end torque. People usually see better results from spacers on 4-cyl's than on 4.0's or bigger.

No way! In what vehicle?i got a 8 mpg increase with this![]()
I think he was kidding. Depending on the application, it may be worth your money. I have heard throttle body spacers are much better on carbed vehicles compared to non-carbed vehicles in addition to what PavementPounder said.

My son in law put one on his 92 Wrangler with the 4.0. He felt a noticable improvement. How much? I can't say.

Every review of one of those "tornado" things that I have seen/read showed mileage decreases in a 4.0l.
