Throtle Body spacers?


Recommended Posts

The only way a TB spacer is useful, is on a TBI, or carbed motor.

 

I am going to agree here. The only thing a TB spacer does is add to the volume of fuel/air mix, and if you are running MPI, it won't work as it would stirring up the air/fuel coming in, and adding a couple of cubic inches of available volume.

He has a TBI motor.

Still a waste of money IMO. For the money spent, there are no significant gains in MPG or HP. I have tried them on 3 different engines in my years and have been disappointed in all.

I have noticed a "small" seat of the pants improvement, but nothing life changing. For the price, if you have a TBI setup, just want to eek out some more minimal ponies, and add some anodized colors under the hood, go for it. They are only about $100.

Sorry. I didn't know that. I've never had a jeep with 2/3 of a motor!

 

86-90 2.5 was TBI. Went to MPFI in 91. All 4.0s are MPFI. :thumbsup:

I knew all 4.0's were MPFI, but I haven't even looked at a jeep 4 banger, much less wrenched on one!
