TR6
I wouldn't consider the colder one till you up compression a lot and add more spray.
If you think the TR6 is a little hot yet try an Autolite 103

For nitrous I prefer a non projected tip. I vote for the BR6EF.

I prefer the br6ef. Non projecting tip is the best for nitrous use. Too many have burned the tips off on tr6 plugs but a good portion go back to the tune as the cause.

How will a plug that cold handle street NA use?
I ask because a HOT cam only 100shot sounds like a car that sees more daily driving than track.

+2 non projected tip for spray or very high compression.......i run a non projected in mine with very high compression NA and i have better results than a projected........projected gives more of a chance of glowing a plug

I like the BR6ef's as well... but all of the part stores even the hub doesn't stock br6's??

The br6 would be fine for drivability in a DD.

Not my daily... VERY LOW MILES only drive it when the bottle is FULL.

BR6 as well....as most have stated before me, non projected tip plugs are for nitrous use.

As far as street use and the heat range, I ran a 6 in mine from 2001 until 2006 with the LT1 casting heads for daily driver duty, and run the equivalent of a 9 with my AFR heads for NA duty
