I want to use some NGK plugs instead of the zex plugs for n2o the problem is i dont know how cold to go i here many people saying to just use 1 step colder the zex plugs are two step colder. Can someone give me the part number to some ngk 1 step colder plugs that i can use for a 50 wet shot of nitrous.

 

50 shot? just one step colder... i believe they're the -7 plugs

 

BKR7E

or

BCPR7E

They're nearly the same plug, so it won't matter which you get.

 

btw just thought I would mention I think the ngk's are much better plug, esp. for the money. remember to stick with the copper core... platinum is junk imo... no good for n20.
