Has anyone tried a TB spacer with the 4.0 TB?
« on: December 30, 2005, 04:40:22 PM »
I have already swaped a 4.0 TB on my jeep (mostly out of nessesity when I killed the AIS sensor on it and it was cheaper to get a comlete 4.0 TB unit from a wrecking yard then to replace the sensor). It has made an awsome improvment but has anyone tried combing it with a TB spacer and a Cone or K&N air filter?

I ran a Cone filter but the drop in manifold vacuum was enough to cause a leaning sitiation and a drop in low-end torque.  Swapped back to teh stock Box and I'm happy again.  Not to mention my brakes work better.

Thats funny I left all the stock 4.0 sensors on it and really didn't notice much of an idle rise. At least nothing that bothered me. So the spacer works good with it but you didn't like the cone air filter? Hmmm thanks for the results.

I suspect that if you leave the 4.0L AIS in the 4.0 AIS housing you won't have problems.  It's when you start mixing and matching.  Although the bypass for the 4.0L is larger.

Maybe, I actually did the swap when I buggered up the AIS on my 2.5 TB. I was doing my tranny swap to the ax-15 and it would start because it had sat so long with a filthy TB and had gummed up the AIS. When I tried to take it off and clean it I messed it up. So I just went and got a whole throttle body sensors and all out of a wrecking yard. Left everything on it (it was way clean already) so I just put it in and it has been my best performance mod so far. I am anxious to add the TB spacer and see how much more that helps though.

I would think that would be dumping too much fuel for the 2.5 WITH the added spacer. ???????

A throttle body has nothing to do with dumping FUEL.
