Maximas only had HID starting in '02.
HID was standard from 02-03.
When the 6th gens arrived, in '04, HID was optional.
I don't know if HID is still optional on the 6th gens, but it very well likely could be.
As for the headlights, if you have HID already, then it's Bi-Xenon (IIRC), and like jltibbs said, you'll need a D2S bulb (but only if you want to change color). Remember that the higher up you go in the K scale, the less light the bulbs put out.
I'm not familiar with the 6th gen halogen headlights, but I was under the impression that the low-beams were simply single filament bulbs. If that is indeed the case, then all you'd need is a single xenon "kit."
