i know that for even a low boost (about 6 psi) i have to use colder sparkplugs.

i have a eaton m62 supercharger with clutch and i want to use it to turn on and off this supercharger so sometimes engine will be N/A and sometimes supercharged...

so my question is what sparkplugs i should use? what's gonna happen if i put colder plugs for N/A engine?

or what will happen if i use standard plugs with supercharger. ( it;s a soft boost about 6-7psi)
