what is your spark plug setup?

i just had my sensors out after running your same mod list for about 5k miles and they are BLACK.
i bet the burble and extra fuel wears them out quicker

cant wait to see your new HP #'s
thanks. I'm excited too. Just hoping I can get on a properly cooled setup with some airflow.

Also important note - it wasn't that I just replaced the first set but one of my sensors was completely fried/damaged. I had a CEL that it wasn't even registering it as. I didn't think it would make a huge difference but it did.

I'm on NGK 97506, gapped to .018. I installed them maybe 400 miles ago along with injectors so basically brand new.
