No problem at all is the nice reply, read my thread, see the performance level, see the durability. WM50 (same thing everyone now is copying on gayclub) pioneer all on R7420 plugs

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?

B*EGP is the one you want to use if you want to stay with the motorbike plug, its just the same except the it has a platinum ground pressed into the alloy plug body just like the expensive rotary only plugs. And there is an increase in quality as you noted due to non resistor amoung other hard differences like smaller centre (and in the EGP its platinum center and ground) its a high quality plug.

For rotaries I run these in B95EGP onwards (colder) depending on application.
If I get time I will line up all of these that have run long term in turbo rotaries and show what they look like.
For the B*EGV I never lost any ground ends like you have but always ran them in 10 and 11 heat ranges only.
