Just a quick question about my car

So I just got my 02 Grand Prix GT and I'm needing to do some small work to it (oil change, air filter needs cleaned, etc.) well one thing I was gonna do was change out the spark plugs. What is the best spark plugs for my car? I'm wanting to go with E3 Diamond Fire Spark Plugs, but I'm unsure whether this is the best bet for my car, so would this or some other kind be better?
 


Stock replacement iridium plugs work best in these engines, coppers work fine too, but never use platinum plugs. Stock heat range as well if there aren't any modifications done to the engine.
 
Yeah the delco iridiums if you're stock and plan to stay that way. Otherwise autolite 605 copper cores, cheap and work fine.
