Colder plug for pulled cobra?

[2003 Cobra Kid]

I am about to put the 2.76 pulley on my car and was wondering if you guys think i should go from the ngk 6ix irdiums to the 7's or just leave the 6's? And plug gap at .032 right?
Thanks, Joe

I'm running the TR6s Copper gapped at .032...I will be getting pullied here shortly...this is the combo my tuner recommended...

i was recommended the 7 series for my old setup, which was stock blower, 2.93/4#.

I run the TR6's on mine. I run the coppers bc I can change the plugs every other oil change for like $20, and they are good plugs

I'm running the tr6ix's gaped at 34 switched from the regular tr6's to these and noticed a smoother idle during cold starts but that's it.

The colder the better. TR7 style plugs are the way. Try listening to silent detonation.
