06 GP 3.8 looking for spark plugs

Hello.

New to the forums as of today. Have 06 Grand Prix 3.8L w/ 107k miles. Still have original plugs in. GREAT CAR!!! I want to change plugs. What plugs should I buy to make this continue to run great, and still get great fuel economy?

Thanks,
Chas

Just get some ac delco iridium plugs and you won't have to change them again for quite sometime.

That. ^^

GM# 12568387 (AcDelco 41-101) Iridium plug is the factory OEM Replacement. Run about $9-10 at the dealer maybe a little less at a Auto Parts Store.

NGK-TR55s can be used in place if you want something different. But I would suggest the AcDelcos.
