Throttle body spacers?

[Darrman]

Has anyone installed a TB spacer? Does it give the performance they say? I am thinking of getting one, along with a custom 3 inch cold air kit, try to get a little more out of street mpg. Thanks!

basically the answer is no, throttle body spacers don't do anything, look up aldive's quest for 30 thread, he has done dyno runs with them, and saw no gain in power.

Lots of opinions on them will be found by running a SEARCH for "throttle body spacer."

Ok thanks, looks like its a no-go. I was already wondering why a plate of metal between the tb and intake plenum would create 22+ horsepower. Good thing I asked, I might have fell for it.

Using a carb spacer in my bracket racer improved low end torque. There was no horsepower gain, but the low end torque improvement was significant. I plan on getting a spacer for my Explorer to gain more bottom end.
