4.0L - Throttle Body Spacer
Anybody try a TBS?

Any noticeable power increase?

Any MPG increase or decrease?

If you have the 4.0 it is nothing but added weight to your vehicle. Ditch the idea.

Will not help a 4.0

I agree, a waste of time and money. I added an aftermarket cool air intake for 30 buks and got way better results than spacers.I also just upgraded my fuel injectors on my 93 4.0, went from regular ones to bosch 4 holes (they spray a mist instead of a stream) and am getting 18 to 20 mpg and better power. They were 100 buks on ebay and well worth it. simple to change out.
