I didn't know for certain, that's why I asked. All I've heard are people spouting that this is how the glow plugs on a RC car work with the nitromethane fuel, they're platinum and it reacts with the fuel causing it to go off. It sounded good to me, I have no direct experience with it. Anything I've ever run meth or water/meth on has been running copper plugs. Good to know that I can run iridiums with platinum tipped ground electrodes.

Another question for you. I've toyed with the B9EGV plugs in the past in my halfie FD. I did notice an instant increase in idle quality and throttle response, but I found that after some hard driving the ground electrode would break off on some of the plugs. It didn't matter if I was running race gas or meth with 91 octane. I shied away from those plugs because of that. Perhaps I was running too hot of a plug? Any suggestions there?
