opinions on iridium for nos

[ViruSi]

NGK iridium plugs still ok to use for 50 shot nos?

 

[evan2]

i wouldnt, iridiums are a waste anyhow its for people who dont want to change plugs
id go copper with any type/form of fi they run colder

platinum runs too hot...

keep in mind all plugs have a range... but in gerneral copper doesnt get as hot like plat does

If you want to spend the money on irridium...go right ahead. But it's not going to improve your performance over Copper core NGKs or Nippondensos. They do have a longer service life but B's and D's are ridiculously easy to change the plugs on.

Irridiums and platinums have a larger heat range variance but they are not necessarily hotter.

Colder plugs are a good idea when using nitrous on a some-what stock engine.
