If it truly improved gas mileage, you should IMMEDIATELY notify Daimler Chrysler's VP over engineering to alert him to this major breakthrough that will help Jeep meet its ever increasing CAFE fuel economy requirements!

Moab Man Put some spacers between the valve cover and the intake tubing to lift that. Didn't have to shorten the tubing above the throttle body. There is enough room under the hood.

Sorry, i was wrong i have the 2.5 in my 97. but just putting on the 4.0 throttle body has done a noticable difference! so i think i will do a 2" spacer and also weather it is a waste of time it will be a grand total of about 20 min becase my dad is fast at drawing and the milling will be a snap 5 holes and a tap. and i will put that on and see what happens. also when you put this on how did you shorten the intake hose that connect to the throttle body or did you just do away with it all and did a straight connect to the air filter. would that be ok because i was thinking about doing that too.

Buster Ok, Now I am confused. I am seeing two very differing opinions from two people that I have valued their advice on several jeep things. This is not meant as an attack or anything of the like just an observation. Bob.

Jerry Bransford It's your Jeep but it's my opinion that you're wasting your dad's time by asking him to make a TB spacer. The one in my junk box I removed from my TJ after it was given to me to try is about an inch high.

mswilder ok i have a 4.0 throttle body for my 2.4. and i am going to custom make a TB spacer. My dad is a CNC programer/operater and a co-worker of his brought in a TBS from his 2003 chevy, and dad drew it up on auto cad, so we will take the design on the inside and apply it to the TBS for my jeep. but to the question at hand, what is a average thickness or height or whatever it might be called for a TBS? I was thinking about 1/2 in, yes/no or what? thanks for your help

shaggy105 I agree with Jerry...complete waste of money...I have 98 4.0L and bought aftermarket intake and TB spacer and noticed no change...however, intake makes cool sound almost like a turbo, so I got that goin for me...

Jerry Bransford TB spacers are, at least in my personal opinion, a complete waste of $$$ on a 4.0L engine. Spacers are marvelous and can boost power substantially when mounted under a carburetor or a TBI (throttle body injection) system where the fuel is injected above the spacer but they don't really help a 4.0L with fuel injection that injects the fuel below the spacer directly into the combustion chambers.

I'm of the strongest possible opinion that they only help by a placebo effect. Yes, I have tried a TB spacer that was given to me and other than a difference in sound from the air intake system, it produced no difference in anything that I could detect. Don't forget, there's nothing but air flowing through it and it can't magically force or allow more air into the engine than the engine is asking for. I have a TB spacer in my junkbox if anyone wants it.

My TBS experience

The first mods made to my 2002 TJ 2.4L were to install a throttle body spacer and an Air Raid intake. My understanding of the TBS is that it increases the volume of air available for combustion. I have no before/after HP tests, but I felt a considerable increase in power after installing the TBS and the intake. Highway driving was improved. I have also installed a Banks header and cat back exhaust. The idea was to let the engine inhale and exhale as freely as possible. The header and exhaust also improved performance - but not as dramatically as the TBS and intake. The engine now has a pretty deep tone - which I like. The most bang for the buck was definitly the TBS/intake.

blueJeeps I have the Power Aid throttle body spacer on mine.
It made some improvement.
I also have a Flow Master muffler and K & N air filter.
The biggest draw back to it is the whistle/whine. It almost sounds like a super charger some times.

throttle body spacers???

what is a throttle body spacer do, or better yet how does it work. how much extra power does it give you(appox), and is it used in conjuntion with some thing else, if so what. and all this on a 2.4 application.
thanks for any input.
