Unless Nissan changed things since my last 350Z, the spark plugs should be good for 100K miles. You're not going forced induction or nitrous so a colder plug is not necessary.
With that said it never hurts to pull the plugs and check to make sure everything is okay and there is no evidence of detonation (knock).
