Plugs with nitrous?-search didnt help
I posted this in the FI/nitrous section but its pretty slow. I did a search and and found 4 threads that have plugs for L98 and N2o. In those 4 threads were 4 different answers. I got NGK BP8EFS, NGK R5673-7, champion 7401, and champion 4113. Which one should I use with my 86 and 100-150 shot? Thanks.

I'm not sure if the brand of plug will make much difference. I think the most important thing is to learn their heat ranges. You will probably want to go with a plug that's a step or two colder than stock. I am running NGK tr6's in my LT1 with a 150 shot.

in my 86 i run a 150 shot and i use AC Delco's that's two steps colder than stock. not sure on the part #, but i got them from autozone. i originally bought some NGK tr6's, but they didn't work since i have the iron heads with straight plugs.

Sorry I'm too late 
At the advice of REDC4CORVETTE , NGK R5737 for iron heads and NGK B8EFS for aluminum. Most auto parts stores could get them overnight.
I'm using the B8EFS and so far so good.
