They can look it up or cross reference it. Trust me... Im a AGM for Advance Auto :-D
Are these the plugs you have on your GXP? I have an 07 grand prix GXP, and I am looking for good plugs to use. I was told to use the NGK 61X, but on the site it said they were not for my car. How is the performance with these if you are using them? I have Bosch Iridium Platinum Fusions in right now. Haven't had any problems, but I want to put in what will be best.
Thanks
