yep... thats about all it does

 

Nope......

 

x2... but you WILL get a great high pitched whistle!

i honestly wish i had found the forum before putting mine on. i feel like i wasted the money

 

As mentioned before, it's not going to provide any help. On the other hand it doesn't hurt anything other than your wallet.

The intake manifold pressure has a sensor and a TBS on a port injected vehicle doesn't do anything to increase fuel atomization. What it will do is very nominally increase manifold pressure under low rpm acceleration. So that very minor little bump in throttle response, and the rest whisked away by sensors and the PCM.

Again, no reason to buy one and if you can deal with the slight whine from them no reason to get rid of one.

 

Holding papers down on your desk.

 

...but I speak without fork-ed tongue.

 

The only reason I have one is it was used and at a cheap price, I have to agree no change that I can find and mine don’t even whistle, as far as a putting it on the desk it’s not that pretty, I just leave it on the jeep so I can tell people that don’t know any better that it’s a performance mod

 

Improves low-end torque and gas millage by a little bit.

 

This is a well distributed myth. The tb spacers do absolutely nothing for the type induction the JK has.

 

this point has been beaten to a pulp on other threads, and i believe redneck, you were the one who provided the scientific explanation as to why but what i read, again after i bought the stupid thing, is that the air induction happens further back inside the throttle body, therefore negating the need or usefulness of the spacer
