Isn't the Iridium a platinum plug? Platinum plugs and nitrous are a no-no.

Why do you say that?

I dont know the heat range of the plug he posted but Iridium is fine for N20 use.

If I remember correctly, that plug is a stock heat range.

Go at least one range colder to be safe. I don't know how a iridium plug and nitrous are gonna react, I know that platnium and nitrous are a bad combo, not 100% on the iridium....

But, for the $ that those cost, why not just get some cheap 2 dollar a piece tr6's and call it a day? You can buy quite a few of those for what it would cost ya for 8 iridium plugs FWIW

Iridium's are fine for N20.

JL is right for 100-150 just throw some TR6's in it.

I daily drive the car and I dont want to chang plugs often at all! I have TR55 in now and they need to be changed so I am going to try the Denso Iridium one range colder on a 150 hit dry! I am going to Simple Quick racing to get this thing tuned next month and see what it puts down N/A and on a 150 hit!
