reply on plugs
i made a mistake when installing the plugs on the intake side i didnt plug the harness together right with the right coil pack.
On the intake side the last two harnesses for the coil pack i had switched.
Make sure that the middle harness goes to the coil pack in the rear and the last last extention goes to the middle
It sounds weird but it is so, that the wires dont get bunched up.....(Nissan made it look clean)

Now what kind of plugs are good. I've heard alot about NGK Iridium. I went to autozone and they had 2 kinds, the NGK iridium or autolite double platinum. How are the autolite plugs? does anyone know?

NGK. 
Depending on your set up, a colder spark plug may be better. Again depending on your set up, a hotter or the regular (recommended) may be better.
If you're N/A and will drive in all normal conditions, the recommended spark plug is your best bet. NGK seems to be the popular brand and their prices are good. Copper ones do conduct a better spark, but iridium and platinums are also good and will last you a lot longer than copper ones.

ok i have a question, generally on spark plugs
just yesterday, i was in my car and i turned the key and the car didnt turn on. you can hear it turning, but it never ignited. Is the spark plug the only possible reason for this? Or might something else be the cause of this? If the spark plug is the only possible reason, then im gonna change mine. Thanks alot

The dealer said the stock plugs were good for 100k miles.
So does the coil assembly have to be replaced at certain intervals?
