NGK Spark Plugs are Standard for all Nissan Vehicles. It is recommended that spark plugs are replaced every 60,000 Miles. For Turbo Charged or Super Charged 350Z/G35 we recommend a colder spark plug #6(PLFR6A-11).
Our new Compatibility checking feature is still being updated and revised. If you have questions about vehicle fitment, please contact us.
Is it pointless to get the colder plugs on a stock G?
If the car is bone stock it's not really going to benefit you much. You could probably argue that a higher mileage car may have some carbon build-up, which generally increases the chances of detonation, so a colder plug would help alleviate that.
i have a tomei y pipe back exhaust on a 03 350z AT . should i get the standard or the colder?
We generally recommend 1 step colder for almost anyone, they don't really foul noticeably faster but they help prevent pinging either way.
I have a 2006 g35 coupe AT base with intake,exaust mods do you recommend i purchase the NGK PLFR6A-11?

Yes, we generally recommend going with the #6 Colder plugs once you have some bolt-on mods.
