Well, you need to give us a little more to work with. What year, OHV or SOHC, what do you want to use it for (street/off-road), budget constraints, etc? There's not a huge aftermarket for the 4.0 compared to other motors, but you can still find performance enhancement/replacement items ranging from better air filters all the way to superchargers & nitrous.

I went with K&N filter and Flowmaster as engine upgrades. K&N was slightly noticeable, nothing major though. The Flowmaster really made a difference and gave it more pep. Rebturtle is right, we need more details.
If you got a stick, a Hurst will make shifting much nicer.

- K&N air filter
- Remove the baffle in the airbox
- Bosch +4 plugs
- BBK 66mm throttle body
- Jet Performance MAF sensor (yesterday!)
The mods I have made so far have all been worthwhile, but none of them stood out as "the" best mod. I definately have more power, especially off the line. Removing the baffle from the airbox was the coolest because (A) It was free, and (B) It makes it sound like you have a really nice exhaust when you put your foot in it!

You should notice a little more pep, and a nice throaty rumble when you open the throttle under load!
