im not too interested in making this thing insane...but i have a 4.0 i6 2000 cherokee, and i was wondering what, if anything has a noticable increase in either mileage or power or both...

whats worth it, whats not, whats best, what doesnt work ect...

what Exhaust?
cold air intake?
throttle body spacers?
ect....what else have yall tried on this engine?

The Edge Trailjammer does pretty well. They say it increases up to 20% horsepower and almost 2 seconds off your 0-60 time. I can tell you that on the ones I've installed, you do feel a different in power and acceleration. We sell and install Edge, let me know if we can help.

I got a 2mpg increase in fuel mileage by installing a Poweraid throttle body spacer, never checked it with the exhaust system as when I bought it the exhaust was broken off at the cat converter. But my exhaust is the Rustys 2.5" Flowmaster cat back with a 40 series muffler. I also got a 1mpg increase when I swapped out my cracked exhaust manifold for a Borla header.

I'd say start with the trailjammer kit, it comes with an intake, throttle body spacer and module. Then move on a full exhaust.

Do a stroker on it. Guarateed horse power gain.

No, it should give you a slight increase.

I was just throwing out a price I had seen. That is a pretty good deal you've got there.
