Hello and thank you for choosing Just Answer.
It's actually a little tricky to repalce the coils and spark plugs. Also the car has individual coils, and there is no reason to replace all the coils. You only replace coils if they are defective according to the code that you have stored in the system.
Here are the instructions to replace the coils and pulgs.

Thank You Adin- I will show this to my friend and hopefully he can do this- couple a questions-where is best place to buy parts- is Auto Zone or similar OK- can they do this in my garage without raising car on lifts- is there a special spark plug socket for infiniti- any other special equipment neededthanks Ursula
Please take my advice.
Do not change all the coils, it will cost you very much money. You do not need to change all the coils. Scan the car and find out which cylinder is misfiring (autozone wills scan the car free), the replace the coil that corresponds to the cylinder that is misfiring. (only 1 coil)
Autozone parts or similar are O.K. to use.
You do not need to raise the car.
It is a common spark plug socket, no special equipment needed.
You are great- can I request you specifically next time?-Now that I know you are so good I will mark the $30 box next time
You absolutely can, just when you are writing the question address it to my name (Adin3) .
Thank you very much, I appreciate the compliments.
Good luck and have a great day!
