for those who have these how do they work for ya'll? do you gain hp from them? what do you think of them on your jeep?

 

They work better for throttle body injected engines. On the 4.0 ltrs the spacer does nothing but make the air travel farther. The idea of the spacer is to give the air and fuel more time to atomize (mix), however in this case the air and fuel meet in the cylinders not in the throttle body.

 

so they are pretty much worthless

 

they are more or less seen as paper weights on these 4.0 jeep engines.
