Personally, I don't know the answer without looking it up, but, I'd wager that unless you're doing other mods, the OEM spark plugs will do the job just as well as anything aftermarket.

Just out of curiosity, what are you looking to get out of new plugs?

"Better" spark plugs really aren't going to get you better power - at least, not a whole heck of a lot. Not unless you're talking about some Forced induction or Nitrous in combination - something that changes the "temperature" requirements of the plugs.

The 370 already has Denso Iridiums in it from the factory. From the service manual:

Make DENSO (iridium tipped)
Standard type FXE24HR11

unless u are doing forced induction...leaning more towards the supercharger, there is no point. When i had my supercharged cobalt and did pulley swap and then blower swap then it was time to change to 2 step colder plugs. But right now for the 370z...it would be pointless.
