Sup guys and or gals. I bought a 99 grand prix gtp for a grocerie getter/family car. This is my first American car I've only ever owned Hondas. I'm here to learn about these cars and hope to have it for a long time.

Welcome to GPF.
No rust its a California owned a driven car. Thanks for the welcomes now to my noob question. Ill be doing a tune up in this weekend and what are the preferred spark plugs for the 3.8 SC engine? And do ngk make a plug thats good for this car cuz I've never had a problem with that brand.
Welcome, guy! Just get stock Delco iridiums.
Iridiums are the factory plugs and copper cores are what the modded guys use as they can be a colder plug for the added power.
Copper will only last 10-15k miles, but look at the conditions and the type of ignition system they are put through.
The delco plugs are made to last the longest and give the best performance for a stock vehicle.
If anyone says iridiums don't last, I'll stab them in the eye with one. Because that's what filthy liars get.
ac delco 41-101 or NGK TR55IX.
Both will work.
