Hey I got 94 Wrangler with 4.0 6 cylinder and auto trans. What are some good performance upgrades you guys know about that I don't have to rip into the engine?? Oh, and it's fuel injected by the way....... Cold air intake - what brand? Spacers for the throttle - what brand? Chip for the ECM? Any help would be appreciated - thanx Oh, by the way, how do I find what gearing I have in this thing since it's got stock gearing and if I ever get the $$$$$$$ with the 35" tires - what gears would you guys say to put in it and what to buy them?????? Thanxs again

OP: I took the liberty to edit your thread & remove the capslock for you.

Nobody likes being yelled at.

should be a metal "tag" on your differential cover, that has the gear number stamped on it. if it is modified, or may be modified, there is a way to count the rotations of the pinion while the tires spin. I've never done that so somebody will probably elaborate.

Intake are pretty much all the same. Ive heard mixed reviews on the throttle body spacer. some intakes come with it. I think Jet is the only chip you can get but not to sure havent looked into it to much yet.

An exhaust/headers will help open it up a little and give it a nicer tone.

kmj153 is right. Im pretty sure you spin the wheel once and count the rotations of the pinion. That should give you a rough estimate of the gear ratio.

Thats pretty much it for bolt on performance wise.
