someone out there knows about this part... I know the only thing that people have talked about are the snorkel removal, silencer removal, and CAI installation. Any help with research for this part would be great!

Hard to find anybody that's tried them, but the only feedback I've found so far is that the whistle (thanks to the usual "vortex") is annoying, and whatever improvement there may have been in power, torque, or MPG wasn't noticed. If somebody here gives it a whirl, I'll be interested to learn how it works out :)!

I don't notice the whistle on the Jeep
:lmfao:

Probably because the WHOLE Jeep whistles about as much . . .
(Assuming means a "real" CJ Jeep, or the modern version- still a CJ?- . . . )

Jeeps aren't the most aerodynamic vehicles on the road . . .

More to topic . . .
This is one of those things that only very few have tried. 
Why?
They are paying off their box and are putting money to more "immediate" issues and desires, namely interior parts, grills, wheels, and the like. Also, many refrain from engine mods till after the warranty expires. Most xB2s are well within warranty parameters.  Throttle body alterations, and the discussions of impact, will come in time.  On this particular mod, I'd look into what folks say about it who drive tCs (they have been around much longer and have many doing engine mods AFTER the warranty expired).  We have the same engine as those, so many engine mods are very similar (differ more in intake and exhaust routing b/c engine bay/body shape) to xB2s.

alright now we are geting somewhere... :D Thanks for the great info. I didn't feel that they work all that well since now days there is no carb to fuly atomize air and gas right at the initial start of the intake, but it still might work beter than nothing since the fuel is port injected. I have had several race cars but all carbed and they seemed to work decently on those and i didnt want to waste my money until i did come research and found out what others have done with theirs. I will check out the TC forums to see how they work on their cars. Whisle part of the trotle body spacer doesn't bother me... superchargers whisle when you have them so it is about the same just without the GO :rofl:

Let us know what you find. Plus, if you get it, it would be great to see a full review (w/ pros and cons).

As you point out, the vortex TB spacer is most obviously suited for carburetor and TB injector applications, not ours where the injection takes place at the end of the intake runners (a lusty distance and at right angles from any TB spacer). Regarding the whistle -- a supercharger whistle occurs whenever the engine is pressed (acceleration), however a TB vortex whistle occurs purely due to air flow, and that can be at fairly low speeds from what I'm told by one owner. He seemed to consider it a little embarassing to have a whistle when street cruising at roughly 25 mph :) (for my Eclipse, that would be third gear)!

As said, I'm very interested in learning what others conclude from trying TB spacers. Personally, I suspect the only style that really makes any sense for our engines is a smooth bore, not vortex. It provides less restriction and more room for flow stabilization (reduced turbulence) following the throttle plate before hitting the air plenum (effectively increasing plenum size). From there to the intake ports, I suspect it really doesn't make any difference.
