2013 V6 Mustang Spark Plug Question

Morning. I am new to Stang Net. Was hoping for some solid answers on what I thought was a simple question. After calling way to many PRO's I still cannot get the answer I need.

I have a 2013 v6 Mustang. I have installed a few mods and will be installing a NX Plate 100 Shot Nitrous System. I would like to buy colder plugs. But exactly which ones? Numbers Exactly. I have tried speaking to NGK, Autolite & 3 different Parts Houses. Not one real life answer.

I will gap them at 0.35. Can anyone give me the exact brand and number for best results please and where I can purchase.

I wanted to write a FOLLOW UP to my question on which plug to use for a 2013 V6 Mustang running Nitrous 100 shot or less.

After days of research I talked to the guys at BRISK RACING. The perfect spark plug is below per their tech department.

SPARK PLUGS - 2013 Mustang V6
Brisk - RR14S - 1833
1 STEP COLDER. Out of the box 0.32 which they recommend for longevity
Non-Projected Insulator

Other Thank Brisk. There are no good choices. The non projected tip for nitrous is very important. Good luck.
