IX 100whp tune plugs?
I am having my IX tuned tomorrow, expecting to get +100whp from stcok. All normal bolt ons for stock turbo, no Cams and no meth.
The question is, I have new stock NGK IX plugs and NGK 1 step colder plugs (NGK R7437-8) sitting in my garage.
What ones should I put in the car for these bolt ons and tune.
What should I gap them at?
Thanks!!!!

I just called the tuned and he said to start with a .30 gap on the 1 step colder plugs. Does anyone have experience with using the colder plugs and gapping them?

I personally run the Denso Irradiums 1 step colder and there was no need to gap. I've heard it's good to run the one step colder if you run mostly race gas or alky/meth. I run nothing but 100oct in my car personally

Just wondering why the tuner is telling me to get the colder plugs then? I know on my drag truck I used the colder plugs to assist with the timing. I am assuming he wants them in my car for the same reason? Since I have them both new waiting to go in I am assuming the colder ones would work better with a .028 gap, but I have also read where the stock IX plugs come colder than the stock 8 plugs. Anyone with IX experience with colder plugs and a reason why?

Like I said, I've read around here that if you run a lot of race gas and or meth then it's good to go one step colder. Otherwise you'll be fine with just the normal plugs.

Right, the census on here is to keep the stock plugs, which I would prefer, but my gut says if the guy tuning my car asks for the colder plugs give them to him!
How about this scenario. I put the colder plugs in for the tune and if in the future it starts to run bad change them to the stockers. Would I need a retune for this? Also, a lot of people have said that I do not NEED the colder plugs, but will it hurt to use them (Except the back pocket of course).
