I'll be running 200 shot of nitrous with brodix t1x heads. Anyone got a part number or kind of spark plug I should be using? I'll be running 110 or c16 through the engine while I'm spraying btw.

Try autolite AR3911 for a non resistor plug

AR3922 is one number hotter, resistor type

The AR prefix is for a racing plug, use same numbers with out AR for a regular plug.

so ar3911 should work?

AR3911 is a cold non resistor plug, I consider this a good starting
point for your application. The worst that can happen with a cold
plug is fouling when you are idling. With WOT and a heavy shot
of NOS, plug temperatures will be plenty high enough to keep
them clean.
