What plugs are recommended for the KB set-up? I am going with 19# and it should be here this week and have TR-6 plugs now do I need to go colder, denso, or just close the gap?

Some will tell you to keep the Tr6's and regap to about 32..Others will tell you to get Denso's IT22's or even Colder 24's..

I have had good results with both NGKtr'6's and with Denso IT20's gapped at 38..I am only running 12lbs boost..13 on a good day with my Eaton

John Mihovets reccomends the Denso'
IT 20's to 12lbs,22's to 16lbs, and 24's past 16lbs..

KB recommends IT20 in one of their tech articles, and in another they state IT22, and they also say to keep the stock gap, so go figure.

Personally, I'd recommend the IT22, and gap them to .028 to .032 (Patrick will tell you the same thing, Mike).
