$35 EBay Throttle Body Spacers?!

[midnightcwby]

Good point.  I was advised by my uncle to just shape the bottom edge of it so it isn't such a sudden transition.  Here is the measurements I took from the spacer itself before I installed it...l

Sorry for adding to a dead topic, but I thought I'd let you know (for what it's worth) that I bought one of these spacers today.  I'll add my two cents about it when it's here/installed.

Sure, go ahead, this thread isn't that old and more the marrier.

i have been watching those throttle body spacers on ebay for a while and they seem to be going up in price unfortunately.  they are advertised for post '91, and i am wondering if they would work in my '89 2.4L.  what do you guys think?

[Jeffy]

Nope they won't work.  You should have a 3 bolt pattern TB on your 2.5L.

Ok, I've been running my EBAY tb spacer for a while now in combination with the 4.0l Throttle Body.  I noticed a good increase in my range after a few weeks of driving. I can now get just over 220 miles per tank.  I used to get between 145 to 190 depending on how fast I drove on the express way and how much wheelin' I've done on the tank.  With carefull, easy acceleration and keeping it under 75 on the express way I can get just over 220, actually I've got like 1/16th of a tank but I'm not too trusting of the fuel gauge in this baby, so that's the absolute lowest I ever let it run.  If I ran it to empty it would probably get like 230 or so.  When I drove like this before the TB spacer and throttle body swap, the best I could ever hope for was like 194 per tank.  The tank has a 15gallon standard capacity according to a website I just googled, so that's a jump from 12.93 to 15.33.  This is actually a little lower because I don't run my tank to dead empty.  I believe I leave like .937 gallons of gas in the tank when I fill up after I let it run down to a 1/16th tank. So, a better estimate would be  190/14 or 13.86mpg before the spacer and tb swap  and 220/14 or 15.71mpg.  Now, this isn't the best the jeep can get, of course.  Lately,  even though I've been very carefull with the throttle as  much as I can, I still find myself haullin' butt off a stop light before I remember I was trying to get good mileage off this tank!  The spacer and TB do make a significant difference in performance, so it's hard not to use it once in a while   And it's been STUPID windy over here lately, so my expressway mileage isn't what it should be because the jeep is getting it's  (at) $$ kicked all over the road.  It seems like I just can't catch a tail wind no matter what I do! :(   So, I'd be willing to bet that if I cut out my in town driving and just stuck to the expressway at 70mph;  I should be able to expect 16 or 17mpg max.

I bought two of these. One for my son's 4.0 and one for my built 2.5. There is a noticable difference once it is installed.

I just installed my TBS that I got from Ebay, 29.95 shipped. All I can say is
WOW! I cannot believe the difference for the price. I have a 95 Auto with 31's
and I have always had a problem keeping 55 with a headwind. Not only
will it keep about 60 with a headwind, but I actually hit 70 going the other
 way! (kinda scary though) Most of the difference is in the low end as I got
 those 31's to make a little noise around a corner, but at 55 I'm at about
1900 RPM so it works out. If anyone is looking for a cheap spacer this kit
was very complete and well machined.

Only problem I ran into was that I had to modify the cable bracket with
my cut-off whell 'cause it wouldn't clear the fuel rail, but two bolts seems
 to be holding it just fine.



Just thought I'd add my $0.02 since there's always less written about us
auto owners.

[midnightcwby]

That's the same exact kit I got.  Worked great for me, did you have to "modify" your throttle bracket to get the spacers to install like I did?

[Jesse-James]

Yes, I had to cut off the rear bolt hole. It's held with two and seems fine.

There is a company in Searcy, Arkansas that manufactures a spacer like this. Their web site is  http://www.aircellfleet.com  On the web site I only see where you can order for fleet applications. The local police and local sheriffs office run these on all of their vehicles. They are even making them now for fleets of 18 wheeler type tractor trucks. The company is booming. There was even an article in the local newspaper today about their success.
If they can do it, I'm sure other companies are doing it as well.

[midnightcwby]

I actually was able to "Adjust" mine with a vice and a sledge hammer, very fine adjustments of course   .   It fits perfecly now, and is held in place with 2 of the 3 bolts as well.

As far as TB Spacers a smooth bore works better than one with screw design on the bore walls. Smooth bore gives you better air transitions. The one with the air blades in the middle also have a smooth bore and the air blades utilize all the air coming in as it gives it more velocity and pressure. It gives performance results though the whole RPM range. I currently run a 2.5L Throttle body that has been slighlty bored. It has a 60mm on top side and 52mm on bottom. I believe its taper is giving more air pressure into the manifold, she seems to be working pretty good along with TBS. I am soon going to swap to a stock 4.0L Throttle body and see what happens. My concerns is that I might lose torque. Its wierd I have a custom home brewed air intake in factory box that is adjustable and when I allow to much air in I lose torque at higher speeds. It has to be adjusted just right. Right now I have it pretty fined tuned and my lil 4 banger has plenty torque and top end as it is. Of course I have other mods. To list a few, catback, accel coil, accel wires, NGK plugs gapped at .037. TBS, Heat wrap on custom intake tube. Ram air from removing head light bezels. Magna flow muffler, etc, etc. Does anyone run a 4.0L TB, and what was your results compared to the 2.5L T ?
