Throttle body spacer for '94 4.0??

[94Jeep]

Looking to put in a throttle body spacer. Any suggestions on which brand to get, where to get, and possible cost  :?:

I have one, I think it is a Helix or something, but they are all the same.  The cost is about $75 and I know national and modern sell them.  Honestly, they do not do that much, except for make a funny whistling nice at about 2/3 throttle.  TB spacers are better suited for carbs and TBI, not MPI engines

Mopac Auto Supply on 16th also carries several brands.

i've got an airraid TBS. like scott said, it basically just whisltes. I've been told if you bore out the screw like air conditioners you will notice a difference. not sure if it works though.

I have a helix, I bought it at Mopac on 16th ave, Don't expect to notice a big difference, but there will be a little.
But, a little here and a little there can add up to be something.
