ok guys im looking to find some more bolt on performance for my 4.0 xj...
What i have already:
1. performance plug wires
2. performance coil
3. cold air intake
4. jet chip (which i don't really recommend with the auto trans...messed with my overdrive)
5. cat back exhaust
6. TB spacer
will be getting performance intake manifold and header soon
was wondering if there were any interchangeable parts off of other vehicles or any other performance parts that would help me get some more power...help me out guys im calling out for your expertise and your help as a fellow jeeper

63mm TB(Leigh's Performance). When you have the header off, knock out the crimp in the downpipe(if you don't get a nice one with the header). Buy a half dozen cans of carb cleaner and use an old toothbrush to clean out the ports on the head when you swap intake manifolds. In the future when you want to tear into the engine, you can then use the 4.2 crank, custom overbore pistons, a bumpier cam, and a good port and polish job on the head.

Rub the engine with cheetah blood

lol, or add Cheetah Chug XE to the gas

#3, #5 and a 63mm throttle body from http://www.strokedjeep.com/ are good

#1 won't help much, but if you are replacing the plug wires anyhow, might as well. same with #2. Don't get Accell though.

#6 is a waste.
