Ricky that's correct. I'm not sure if the NGK BR7EF is the same heat range as a stock plug. If it is then yes people ( well me blown blue and a few others are running one range colder in the number 7 hole. If the BR7EF plug is Infact a stock heat range then the NGK B8EFS would be a range colder then that.

heat, and the predetenation that it causes is your worse enemy when spraying nitrous, a good wet kit and some fuel additive help a lot, but running a colder plug is an important safety measure too...#7 run hotter than the rest so you put two steps colder in that cylinder and one step colder than stock in the rest.

The tr5.5 is the stock heat range. The TR6 is one step colder. The BR7 are one more colder. Higher number colder plug. As for racing plug or non resistor, they will mess with your charging system and your gauges. The NGK tech told me that and I didn't believe him, he was right. As for one colder in #7 good idea. As for location of spray nozzel should be as far away from TB but after MAF on wet system. Alot is talked about fuel puddling, with a 150 shot you won't have that problem. I've run as much as a 250 shot on a single nozzel, the problem is #7 will go lean on a big shot. The system I like the best is a single plate that goes right after the TB by nitrous outlet. It swirls the spray instead of shooting straight to the back of the intake. You can spray 300 with good distribution. I use it on my twin 70 mm turbo with 16lb boost. Foot brake it to 2300, hit it with a 150 shot right off the line, let off before 1-2 shift. Makes 1300 flywheel hp. Best et 8.98 best mph 161. Weighs 3800lb.

By the way I get all my plugs from Oreillys, about $2 each. If they don't have them in stock the can get them in one day. I like the NGK the best. I see your in Orange County, I'm up in Bakersfield. We raced at Pomona in an NMCA event last Sept. and won true street class. You might be interested its for true street cars, alot of fun. They have awards for clossest to 10.0, 11.0, 12.0 all the way to 15's.
