I was thinking of a doing a TB spacer, but was wondering
A. Is it worth it? any experience with MPG gains or performance gains?
B. Is there a brand thats going to be better then others?
Thanks!

 

i am interested in this myself so i will be watching

 

save your money for something that makes a REAL difference like a ported TB from http://www.strokedjeep.com/pictures.html or a 99+ Intake manifold + Injectors.

 

Yep TB spacer will do nothing but add some whistle to the jeep.. I am 98jeepjeep get a bored TB or the 99+ intake mod and some new injectors...

 

I have one it made a very slight difference. I don't think a spacer alone will do much. But if you want one buy one from ebay and save a few bucks.

They do make a slight difference, I know of 2 cherokee's with them and they gained a small bit of power but the difference is in gas mileage for some reason. I think it was about 1-2 per gallon. One is on a bone stock 2000 and the other is on a lifted 94 with 32's.

I am going to put one on mine, as soon as I find a good deal on one. Poweraid is the one both of the rigs above have.

Look at this for Better info.http://www.off-roadweb.com/tech/0812...mpg/index.html

 

waste if money. Save for the big gainers, intake and exhaust (cold air intake and exhaust).

 

Only prob is the XJ has a 4.0 not a 5.2L or 5.9L engine..:P

 

do you know where i can find headers. i have looked but all i can find is for the 97. i have the same enging but i dont know if the spacing is largly different. i can trim but to what extent am i going to be trimming?
