Spark Plugs?

[gahris]

I'm going to be changing my original plugs on my 2006 GT S/C. The plugs I picked up at a local parts store are
ChampionSparkplugs.com - Application Search Results
Champion Iridium Plug 9404 .060"

They say they are OEM quality, Does anyone have experiance with these plugs at all?

The GM dealership wants me to buy plugs that are twice the price! He says anything but GM brand plugs will cause misfires?

BTW - 0.060 gap right?

yes the gap is .060 do you plan on modding it at all? If so go with a copper plug.

They're decent quality, not great by any means.

You could put Honda plugs in there and it would probably fire. Just because they aren't AC Delco doesn't mean sh!t. Get some Autolite 606's. These cars love copper plugs and run great on them.
