Increasing Power and Performance

[TinytimTony8]

I was looking for some simple and affordable ways to increase power and performance in a 4.0 V6 OHV engine...

Start with the tune up stuff first. Plugs, wires, etc. Then if you want to build power get a catback exhaust, throttle body, intake, Computer chip, and if you really want to see power. Most people on here say to switch the fluids over to synthetic and they mean everything not just the motor oil. This includes the trans, differentials, transfer case.
