I was looking at going with the NGK TR6IX plugs, but think I'm going to go with the AC Delco alternatives 41-104 (iridium). They are also one step colder than stock gapped at 0.040" and what is used in the LSA/LS9 motor. I've always had no complaints with Delco's in my other vehicles.
I've read that i should gap them to 0.035" is that correct? Right now I have some junk champions in the car from when I bought it used. Keeping in mind I have a Maggie.
Also for anybody interested.... there is a wicked rebate going on for these plugs too. $2 mail-in per plug !! rockauto has the plugs for $4.71/each. So for $38 worth of plugs minus $16 it's only costing $22 + shipping. Rediculous.
Here is the rebate form. Looks like its good until december 2013!

Look up 2010-2011 CTS-V spark plugs and they will be in the ignition category (there is no hardlink)
