Hi, should i run 2 step colder or 1 step colder plugs for 9psi? I have full MSD ignition and i have a 12:1 FMU stock injectors with walboro 255 hp pump. Rev Hard 2c kit.

Is it bad to run too cold of a plug? other than fouling...thanks

 

2 steps will be fine. So just run a heat range of 7.

 

does anyboyd know the part number for 2 steps colder ngk plugs on a B18B?

 

ngk bkr7e

 

for a b18b, it should be zfr7f-11

 

so is it the zf or the bk?

what plugs should i run on a h22a 8 lbs drag kit, i am currently running stock platinum, is that bag, it runs great, gas milege is horrible

 

so is it ZF or BK for B18B LS motors?

 

i know, i want to kno which NGK's are 2 step colder for the b18b

 

Do a search. I just posted a NGK chart a few days ago.

 

I've ran both the bcpr7es and bkr7e in my LS motors and they both do fine.

 

 

do you gain/lose any hp using 2 step colder plugs compared to just 1 step colder?

pros and cons of 2 step VS 1 step colder plugs?
