Just checked my manual, which may be different from LongBeach's car, but I doubt it. It calls for a Bosch 7 or Champion 9. 12 is WAY too hot for a turbo whiteblock application, no matter how you look at it.
Yup, Champion RC9gyc is good for stock, if boosting a bit more, champion rc7yc is ideal.

When you are talking about champion plugs, 7 is colder than 9.

Well monkey me running, I was way off with regards to champion and bosch. I stand humiliated and corrected. And 5 ranges to hot is much worse that 5 too cold.

not sure especially due to the fact that I found his original problem, and I stated that climate has nothing to do with spark plug heat range THAT much.

Pinging is first detonation sign, sounds like somebody is playing with will metal balls inside compression chamber.
After a while your piston becomes those little balls.
Guys just use oem plugs gap them and you have nothing to worry about.
