Going to be running 150 shot plate fogger, what plug do you Nitrous guys recommend? I would think 1 step colder should be fine? But there are several options and im new to this motor setup. Any help would be appreciated!

Try the Denso IT22. It's two ranges colder than stock and ought to work great in an LT4 with a 150 shot of nitrous.

I use the IT22 in my LS6 and LS7 both of which are modified. Also I used it in the modified LT5 I had in a C4 ZR1, again to good results. It ought to work great in a mod'ed Gen 2 LT4.
