2004 Pontiac Grand Prix GTP

99.9% of the time I want to just drive the car, not race!

Do you have a link to those?

Sparkplugs? Need those now.
I was advised to get TR55 by Jameslvey24. That's the only suggestion I got other than to make sure they're copper which I'm having a hard time with!
I'll get these ACDelco wires, just unsure of the sparkplugs! http://images.tapatalk-cdn.com/15/06...ee3f7d2da2.jpg

Enough of the back and forth stuff here, if you want to be at stock as can be with no questions on quality of parts and the best performance from said parts, buy the stock spark plugs.

AC Delco 41-101 Iridium plugs are the best plugs hands down. GM wouldnt put them in the cars if they didn't think that. They are good for 75-100k miles. Those AC Delco 7mm are stock replacements aswell and are the best quality for a stock vehicle, again GM decided they work great and they are proven to do so.

Ty, I just have no Owners Manual. I'm putting a lot of trust in this forum as I've always believed the best advice is from the owners themselves!
