Thread: Traded 04 grand prix for 06 grand prix GXP with 42000 miles

I'm such a noob. Speaking of this thread...stock AC delco plugs are crap for the gxp. I went one heat range cooler so much better.
NGK-TR6IX and MSD wires

v8 uses platinum plugs dont they?

Marines, you're just as much of a noob as the rest of them.

No forced induction, no spray. No need for colder plugs. Your plugs were probably just crappy.

Go home, you're drunk.

No two ride threads.
