Lightbulb Spark Plugs?

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.

Looking at the 2008 G6 manual it is recommended at 100,000 miles to change the plugs and inspect the wires.
