thanks

For the money you would be better off buing something esle. :2cents:

i've never seen them on imports, i think they're mostly for domestics and v8 engines.

I wouldn't buy it.

Ok i guess i will fess up. I bought a throttle body spacer for $118 from a local shop. I installed it in like 10 minutes. As fas as performance there is no difference. But i did get a little better gas mileage. Plus it makes a cool hissing sound. A LOT of people as me if i have a turbo. It makes me sad when i have to tell them that i don't have one. I wouldn't buy it again if i had to do it all over.

Thank you for providing the helpful information. It is always more helpful to some people to hear something from someone who actually has a particualr product vs someone who does not have that product. :bigthumb:

So all of this is just BS?

On a race motor that might happen but on a street motor yes it is BS.

How does a throttlebody spacer actually work? What is the theory behind these things? I dont know anything about them.

The spacers are suppose to spin the air comming into the intake manifold and mix the gas better theoretically making more power. If you look at the throttle body space it has a spiral design in the middle.
