Anyone try Iridium + nitrous... I was talking to a buddie of mine who owns a shop and he said that they have dynoed a couple of cars back to back with copper vs iridium plugs and seen gains. 8 - 20rwhp Anyone try them? Anyone have a PN for an iridium Bp7EFS non projected plug?

I've thought platinum & iridium plugs is not good for nitrous usage. They are more long-lives, but there have poor spark...

Iridium resists heat 4-5 times better than conventional plug material and are WAAAAAYYY better than platinum. They're an ideal nitrous plug as long as you select the proper heat range. Only downside to them is cost, but if you want to run well on motor and the spray, they're worth a serious look. I'm running TR6ix's.

I've talked to NGK about those plugs, they are recommended by them for being safe now for juice. Make sure you get one or two steps colder.
They told me one step colder if you are going to 100-125shot
150-200 shot, go two steps colder.

Did you ever have a Yank SS3600 converter in the bunch you have owned? If so what rpm do they like to be stalled at? I had a Vig 2800 that only liked launching off idle. The SS3600 feels much better between the two.

I'm currently running the TR6ix's... I haven't had a chance to spray them yet but they appear to work fine for me N/A. I was told by a couple of people that this would be a very good plug to use on the spray.

By far the best nitrous plug you can buy.

Yuck
Autolites in a GM are a recipe for disaster.
