NGK Iridium IFR5E11...Cold Enough for Nitrous?

[Tyrell Corporation]

I've been buying the V-Power NGK's forever now, but the Iridiums seem to be the recommended plugs for my 240.

As the title says, cold enough??

5 is a pretty hot plug man, your going to want to step that back if your going to go nitrous.

Can anyone recommend a part number?

I am fairly certain I will have to special order...

Thanks.

Need recommendation for a colder NGK plugs, please.

Should I just go with the V-Power? They are going to be easier to find in a cold plug, I'm sure.

Yeah, I know the part numbers for the V-Power...and I know the number designation assignment for how cold the plugs are; 5, 6, 7...

I was really just asking for part number recommendations for something other than the normal NGK's, something that one of you would recommend over the normal (V-Power, etc.) types. Platinum, iridium, etc.

Guess I'll stick with V-Power.
