I would run the NGK BR7EF which is a #7 plug and non projected at .028-.030.
Why? Why not, because it is non projected which should be used in all nitrous application so there is less heat on the plug and also because it will basically cost you nothing on motor.
good luck.

thanks! I already run the TR6s gap at .39 to keep detonation down and my tune seems to stay on target with them,even NA.
I was curious if i needed a colder plug with my different setup.

Autolite AR3934 would be a decent plug, little colder then most of the guys will tell you ya need, but for the setup in the OP's sig, it would be fine. Just make sure you idle and part throttle timing and a/f are right and it should stay clean enough to not foul out.

TR6 on spray is too hot for a h/c car.
The 8 might cost you a little on motor..But it won't be significant. And if you're really wanting to get the best numbers on motor for some reason, just throw TR6's back in.

I ran the TR6's gapped at .38 with the 100 shot. I upped the shot to a 150 and changed the plugs to BR7EFs. I data logged it with no other changes and I had no knock and no timing pulled.
I suggest the BR7EFs.
