it's very odd that the service manual and owners manual are both silent on these two things.....unless i missed the section entirely. maybe i'm wrong but i would imagine they recommend it around 125k miles at least.
i also just downloaded the service interval manual from infiniti and it doesn't even mention plugs at 105k (although the service manual does) and it stops at 120k so whether they recommend the timing belt after that is unknown. this is very vague....very....

As for the service intervals, you're supposed to just repeat from 3k.

RedBaron - thats what i'm hearing on the chain the more i look. i guess you just do the pump if it ever leaks, but i'd hate to have that fail on me while i was on the highway.
the plugs were listed in the service interval guide, not the owner's manual, my mistake.
oh and the service manual says they are 60k intervals for the drive belt, i thought it was 30k.

Amazon is suggesting the Dayco 5040810 belt instead.
Stupid website...
If I go through the steps of finding it myself, it says it fits.
If I use the link above, it says it doesn't

Replaced my belt this weekend..... just a few comments.
1) 7mm allen wrench doesn't fit in the G.... 6mm was the correct size
2) There is less room in our G's than the pics above from the Z. You literally need to push back on the fan motor in order to get the breaker bar in that slot
3) Found it easiest to get belt back on by removing the plastic cover under the car (same one for changing the oil) and starting with the auto tensioning pulley and then completing the rest of the lower pulleys and finishing up top. (extra pair of hands helps a lot for this)
Just my 2 cents... hope this helps!!

Replaced my belt just now. Have an 07+ G35 4dr sedan V36.
I followed the great directions and pics from above and have the following to add -
1.) 6mm is correct on allen wrench as noted by TomPeters above.
2.) Used a 1" box aluminum 36" long piece of tubing as a pry bar to push the fan motor back - it needed to go over an inch (moved it towards the front of the car away from the engine) to get the 1/2" breaker bar to go into the slot.
3. It was easiest to remove the passenger side air box (1x10mm bolt and it pulls right up out of the way) to get room on that side to route the belt properly around the power steering and alternator (#1 & 2 in diagram) pulleys. No need to remove the plastic splash shield under the car. My wife held the belt in place on those pulleys while i finished routing the belt around the other pulleys.
4. Did everthing from above and took about 30 minutes...with help from an extra set of hands by my wife.......

IIRC my breaker bar for pulley just fit and didn't require me to push in on fan motor. Using some ramps, an electric screwdriver and pulling bottom shield off makes this a quick an easy solo job IMO.
EDIT: I would have waited until 60K miles but I was getting some belt chirp at startup that went away with belt replacement.

I used the factory 2007-2008 Nissan belt. Correct Nissan P/N is: 11720-JK20A.
I bought mine brand new for $39.95 (+6.95 S&H) on fleabay:
