What NGK copper sparkplugs?

Not quite as easily as it can break the tips off the plugs haha, but a valid point. It's almost certain that if you are tuning for the edge that you will knock at some point (hopefully just once on the dyno) but I'd rather know my plugs not going to crack if that happens.

Carey, did you re-gap your iridiums or leave it like it was out of the box? I left mine at the .030" pregapped setting. If you did, what did you gap them to? I've heard that gapping the iridiums is very hard and you can damage them. As a matter of fact, Adam Blevins my tuner/friend was tuning a civic the other day with a new set of NGK iridiums and when they went to gap them before putting them in (they were brand new BTW), the iridium tip broke off one of them. Thats messed up. That tells me that it is possible that they can break off into the engine. What do you think?

I have no idea why anyone would even run a non resistor plug? Why? Especially in a car that came from the factory with resistor plugs. 
I understand the difference in materials, heat ranges, etc. That's a legitimate reason to choose a certain plug, but putting non resistors plugs in an S2000 is beyond me??? Hell, it obviously works for some people, but I just don't get why you would choose to go that route?

I always gap them down. My car won't run at all in boost at the "pre gapped" setting. .023 is where we ended up IIRC. Before I upgraded the ignition we tried a bunch of different gaps and none helped...haha.
It's the water in the water/meth that puts such a strain on the ignition.
I've never seen a tip break off in a motor. But anything possible I guess.

I dont know why either Carey. Thats why I am trying to stay with either the iridium BKR8EIX's or go with another good resistor NGK plug. Do you know what copper plug that is resistor will work well if you were to go that route? Whhich copper would you use? Would the one I listed from the NGK website work on our engine if the measurements are all the same? The R7233-8's I mean.
I ran coppers back before iridium plugs were introduced. But since that day, I've not ran anything but iridiums.
Well, if you are still using the BKR8EIX iridium's with no problems, I may just stick with them since I havent had any problems either. Adam Blevins just suggested changing to coppers since they supposedly have a stronger spark. I'll just gap mine down to about .023" then too. I had gapped my iridiums before but didnt on this set to just see what would happen at .030" and they worked well there. I'll gap them down for the e85 though.
BTW, are you using the BKR8EIX's or are you on the 9's?
Thanks for all you help man. And from everyone for that matter.
Keep it coming though. This will be good info for the future.

I ran 8's last year.
Not sure what I'll run this year yet. I have like 10 sets of 8's I might get rid of for cheap if I end up going with 9's.
Also, I'm not trying to go against what Blevins has told you, I'm just speaking from my experiences. I know those DSM guys love copper plugs.
