NGK bkr6ek plug for boost?

[68ChargerJMP]

It looks to be the same as the factory bkr5ekb-11, except one step colder and its gapped at .036 instead of .044. It has dual electrodes also. Im not having any detontion or pinging that I can hear with the bkr5ekb-11, but just wanted a little insurance.What do you guys think? Thanks.

Worth a shot, why not? I almost went a two-step cooler copper plug with dual electrodes but decided against it since there was no documentation of anyone trying it before so I went with what's known to work.

Should not be needed at such low boost. Closing gap helps if blowing out spark but again never noticed this till running 25+psi.
