Im currently running a nos wet kit on my b16 and spraying a 50 shot. 33nitrous/19fuel. i just burnt up my stock ngk's (part # BKR6E/6962) I went to the advanced auto and the only thing they had in stock were the BKR6ES-11/5553. My question is are these plugs going to be cold enough or do I need to order some new ones. I have done a little research and seems everybody is running the BKR7E-11 or the BKR7E and gapping them around .32 depending on how much there spraying. If the ones i have will work, should gapping them at .32 be fine.

 

the 6 in the part number is the heat range so bkr6e and bkr6es are essentially the same. you will need a 7 if you are looking to go a step colder. for a b-series the bkr7e, bcpr7es, and similar will all work.

Thanks, i appreciate it. That sucks i have called every parts store around here and now body has them in stock. I guess i will have to order them. thanks again.

 

well you may want to take a look at this thread. https://honda-tech.com/forums/forced-induction-16/bkr7e-discontinued-2544828/

the old part numbers have been discontinued so make sure you are asking for the right thing

 

appreciate it. I went to ngk's website and got the new part number for the old plugs and ordered them today. What do you recommend gapping them at? I've seen several people saying around .32. I guess it probably matters how much you are spraying.
