NGK BR7EF's

I was thinking of getting the B8EFs. Not sure if the 7's will be enough
Why 3 steps colder? I think the BR7EF's should be good enough. They're less than $20 a set at Advance Auto Parts.
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?
When Lethal first recommended these plugs, i was a little I was a little skeptical since the HT0 i was used to running in my GT were 4 times the price of these. I am glad to hear everyone has great success with them! Just got my pair in the mail and will be changing mine in the next couple of days.
I ended back up at the tr5s when I ran e85, was only running 6# but the colder plugs had a horrible miss
I run the TR7ix out the box in my KB cobra @ 19lbs.
x2, I run them and I run 80lb injectors and car idles like stock and a/f is around 14.5-15 at idle.
7's should be fine.
