Good day. I have a 2002 Infiniti Q45 and I need to change the spark plugs. It's throwing a P0306 code. Can someone tell me the numbering layout of the cylinders? Thanks!

Sitting in the car, looking out the windshield is our reference POV.
The left bank is the odd numbered one. The right bank is even. As a rule of thumb, Nissan V8s are like that. The V6s have the #1 cylinder on the right side.

So, coming backwards from the front, your cylinders are:

Radiator
1
.....2
3
.....4
5
.....6
7
.....8
Firewall/windshield



In the future, in case you need this type of info urgently:
Do you have a copy of the owner's manual? All Nissan manuals I have dealt with usually point this out in the technical and consumer info section where the engines are sketched along with spark plugs, oil, and other maintenance info.
You can get a free PDF copy online too if your car doesn't have the book.
