Crazy thought here. If one TB spacer is good, why not two? I've got a '97 so I should have room. Has anyone tried this before?
More than one Throttle Body spacer?

Did you notice any change with the spacer? Personally I have heard they are snake oil aside from changing the intake sound a bit.

Who said that one was good?
I don't know anyone who actually noticed a difference after installing one.

Agreed.
In the old days of naturally aspirated engines, adding a carb spacer could gain you performance and horsepower. All that due to giving the fuel more time to ionize with the air. Remember, liquid gasoline does not burn, the vapors do.
But with a multiport fuel injected engine, the fuel is injected straight into the cylinders. All the throttle body does is control air. How could a spacer make more power????

Good points yudaman and toms. I've guess I've been reading too much of the manufacturer propaganda on the web.
I picked up a used BBK Throttle body, and the previous owner included a throttle body spacer with the TB.
I was taking a look at it, and the ones that are sold online and I was thinking that it would be pretty easy to bolt a couple on together, which would make the plenum larger which would give me...
more horsepower?
even better gas mileage?
A higher pitched whistling sound?
Then I was thinking that somebody here probably already tried it. Not being able to find this in the search I decided to throw up a quick post to check the temperature on this.
Since it came with one, I'll bolt it on and see what happens.

That aftermarket throttle body may need the spacer as an adapter. Is it bigger than stock?

A larger throttle body will provide better performance as it will increase the amount of air going into the motor. I see limited benefit of a spacer as Yudaman indicated above. For my Shelby, I went to a larger twin blade setup with a larger intake tube and did the swap on a dyno, and we saw a 50 rwhp increase without a new tune. Don't buy the snake oil
