4cyl preformance mods

I was wondering what mods anyone might know about that will improve HP and torque? Ive been told a few (throttle body spacer) (cold air intake) (preformance coil) and (heavier plug wires) what I need to know is does anyone have any brands they would recommend? Also I need to know if the coil can be done by itself or if you have to do any other mods at the same time to make it work.

Depending on what tire size you wanna run, look into regearing. Thats probably gonna be the most expensive BUT most effective performance gain you can make. I also have TBS from PowerAid. I went with the 4.0L version and to be honest didnt see much of a difference, but than again I was expecting much of one either. Also did a Flowmaster exhaust setup that I really like, Flowmaster mufflers are tough as hell and they give off a nice throaty sound. Check into getting sometype of K&N air filter. I was actually thinking of getting rid of the stock airbox and going with a Airaid Air intake system with a splash guard. Now dont look for one of these upgrades togive you vast improvements, their not going to. But a doing a couple could make you notice a small diffrence. But if you want money well spent, do the regearing.

Blackhole is right. Most of the mods (gimmicks) arent worth the price. I ran a K&N air intake and a dynomax ultra flow muffler and didnt notice much of a difference on my old 4cyl. A regear, which I also did, is the only way to get better performance out of the 4cyl.

I just recently installed a Jacobs coil omnibox, not a great deal of power, but i am getting about 50 more miles to a tank of gas, and its a smoother acceleration, and no knock sounds, easy enough to install, just a couple of wires to battery and one to a hot thats on when key is on and also when starting, that was the tough one to find. I finally found one that goes to the rear window defogger, ( can't figure the reason for that one, I have a soft top). then the wires from coil to distributer.
I also have a TB spacer, magnaflow exhaust,pacesetter headers,turbo city air intake(modified with some original parts) and a larger diameter catalytic converter.
All this stuff has gone in over a period of time, so I havent noticed any big jump in power. The next thing to look for is replacing the TB with one from a 4.0.
Once I start I can't stop.

Wrong. A regear will certainly be the best option, but a high spark ignition in combination with a bored TB, cold air intake, spacer will make a difference in acceleration, smooth idle, better MPG and less downshifting at HWY speeds for passing etc. Argue if you must, but I have the proof under my hood.

Now, if you're looking for low end power for crawling and low speeds, the re-gear is the only way.
