Hello everyone. I have about 60,000 miles on my G6 and I was thinking about changing the spark plugs in it. I didn't know if there was a certain kind I should buy or better yet a spark plug that I could buy to get some more performance out of my car. I would rather replace the spark plugs with a higher performance plug if it is at all possible...

Tell me what you know.

Thank you everyone!

The car comes with a higher quality platinum sparkplug to begin with and should last at least 60k miles.

Here is a discussion on the same topic.

AC Delco makes good plugs. Take a look at the manual to see exactly which one is needed.

I know my GTP with the 3.9 came with Iridium Plugs, and are usually not recommended to be serviced until 100k or even 150k if they even recommend replacing them.
