E85 n/a 12.3:1 LS1 what spark plug, projected? non projected? etc...
I tried a bunch of searches but couldnt get an exact answer. From what I gathered a non projected NGK 7 plug should work out?

Motor is 12.3:1 N/A 346 ls1 with stock ecu and ignition/coils

My question is should it be resistor, or non resistor?
What gap should it be set at?
What is the difference between projected tip and non projected tip? (ie how does it affect the engine)

Also the exact part number would be great...

Thanks

I'm not sure what e85 does to spark plug selection, but if it were on gas I would probably just run a TR6 if it's staying n/a. I broke my 12:1 nitrous motor in with those plugs and it did fine. If e85 needs a colder plug, next in line for NGK is a br7ef.

E85 needs a hotter plug compared to gasoline.
