What spark plugs should I run for a 75-200 HP shot of N2O? Part numbers would be great. The heads are new to me and I'm not sure if they take a different plug then the old stock heads I replaced.
Thanks

I'm no expert by any means. I've been told for my application (454 & a 400 Big Shot) that three ranges colder was advisable. I use an NGK with a 7 heat range. NOS (not n2o) seems to prefer NGK, or at least the Tech I spoke to. Generally, I've been advised to use a plug 3 heat ranges colder than stock (for a 400 shot), so you could probably get by with a plug 2 heat ranges colder than stock. Also, remember to gap appropriately, about .030-.035. Good luck.
