I run the br7ef plugs and ive had good luck with them.
bob kurgan highly recommends them. he has tuned my car 2 times with different combo's.

I was thinking of getting the B8EFs. Not sure if the 7's will be enough

Pull the plugs after a full throttle pass and check the timing marks and read the plugs. They will tell you if it is too hot. You just have to read the plugs. What fuel are you running, how much boost, what compression is the motor?
BR7EF's on 10.5-1 and as much as 14#s of boost on E85 so far.
No complaints at all........
If you have having idle issues that is in the tune and it might need to be adjusted. I run those plugs with 160lb injectors and a big turbo and my car idles like stock.
7's should be fine.93 octane and 100% meth with 22lbs motor is 8.5:1
C16 and meth with 30psi
