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.

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
