Be specific please... It was ONLY the Denso Iridiums (Which I tried and they DO suck)
The NGK Iridiums are very good though.
i have also used NGK iridium with success. bkr8eix-11 i believe is the #8 plug in iridium.

Maybe... but you wont see me putting an iridium or anything but an NGK copper for that matter in anything I own or tune.

I've NEVER had a problem with an NGK copper. I have seen issues with NGK iridium's in some K series applications and they don't offer any benefit. I'll stick with what works, I'd rather not pay 10x the cost for a cool name and no advantage.

I agree the motors are very strong in their stock form.

Either there was an existing problem you were unaware of, or a part failed.

NRG isn't a noob when it comes to tuning, so I don't think thats the problem.

No point in speculating until you get it pulled and see where it failed.

Of course...I only run #8 vpower racing plugs which are copper. I would rather foul these plugs and replace them since like you said they work like a charm. I had iridiums in the car on the original tune @ 8psi and they were fine. Switched to coppers and it ran just the same

aluminum on spark plug means detonation cause it... what cause the detonation is another story.

Can't believe I'm the first one in this post to say this... Miller doesn't exactly have the best reputation for a tuner or engine builder. There are quite a few horror stories floating around about his work, including the time he installed a set of k-series pistons backwards for a customer.

Do a quick google for NRG Tech and you'll see I'm not just some trash-talking troll. I typically keep my thoughts to myself, but in this case it seems you didn't know...

Im sorry I dont agree with you. The stock motor is proven as in every other day someone is making 400-500whp on a stock internal engine with a 3mm HG or stock HG. I dont see how one guy like Jeff can make 701whp and then this car blows up @ 10psi. We know the internals can take the abuse, we know the tuner is good....so it was something out of the ordinary. I run 10psi every day and beat on my car....engine seems ok to me. So Im gonna go with this is the exception and not the rule. I know you like to disagree with me, but I have a valid point.
I've put allot of miles on 10psi, I'm SC though too

NGK doesnt make a copper resistor plug one heat range colder then stock 7 so the alternative is the 2668 NGK irriduim.

I don't believe that it was his tuning ability that caused the failure. I can ask him for the timing and fuel maps if you really don't believe me.

Or a non resistor plug. Unless you have wiring issues you do not need a plug with a resistor. I have more electronics on my car than anyone on this forum with the exception MAYBE of tony from T1 who I doubt runs resistor plugs in his car. I also run non resistor plugs in my DD S2000 and have no issues with either car.

Technically that's not true anyway the plugs out of a rotary (surface discharge) are resistor and would work in our application.
