Heat range colder than NGK BR7EF???
Looking for something in the 8-9 heat range but as a resistor standard (non projected tip) plug......anybody know of anything.....autolite or ngk is fine.....
I'm assuming some of the Nitrous/ forded induction guys may know..........

i set the motor up a bit different this time.......basically the same top end but I did a few things to the bottom end.......the cylinder pressures are through the roof

I just can't see that... I run BR7's in my boosted truck running 15 lbs and a 100 shot. I have no problems with the heat range.
besides the guy at autolite isn't gonna say, "yeah, those plugs are just what you need!!" no he is gonna say you are in need of such and such plugs, which btw are autolites. Im not saying autolites are bad or anything; just saying take a brand manufacturer's advice with a grain of salt.

These should both be 8 range plugs but they are gasket style. I run the NGK 4554's on the 200 shot
NGK 4554 - R5671A-8
Autolite AR3934
