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
 


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.
