Default Which/where spark plugs for boost

Hey guys. I'm sure it's been talked about. And I'v done research and can't find anything concrete. Which spark plugs and part number do I need to run if running a procharger kit. At about 12 lbs. I know the c7 plugs are different? ?

If u guys can let me know which I need to get. And where I appreciate it.

Thanks

Brandon

The NGK 6510 Iridium plugs have been popular. However, there is controversy on the ability to adjust the plug gap without damaging the iridium tips, so some recommend not to gap them and run them with the gap right out of the box. But different applications and boost dictates varying gaps.

Will the 6510 be enough for 12 lbs boost? I figure people will run that plug while on 7 or 8 lbs?

I was told the other day to run part # LTR7IX-11. It seems like a pretty cold plug to me. I will be running a ECS kit, no restrictor plate, TS LT's, and meth 700rwhp/700tq. I believe procharger recommends those plugs as well.
I couldn't find what plug the c7 Z06 is running.

They sound cold if you have a daily driver. I haven't pulled the trigger on them yet.

re above post: the new lt1 and 4 spark plugs are different than all the older stuff because of the d/i have a longer reach and 3346 and 3690 do not work.

the tr7 iridium is full name ltr7ix and stock number 6510

I believe so, as some are running the stock plug at low boost.
