Default Random spark plug question concerning #7 and #8

Since there is an issue with these cylinders running hot, wouldnt it make sense to run a colder plug on these cylinders? Just brainstorming.. discuss!

I would keep the same plugs all the way around... Last time I had mismatched plugs my car ran like *** and sounded like it was missing and and kinda idled rough. Now if I change 1 plug I change them all...

Yeah, running the same plugs all around is the way to go.

It's better to have the fuel injectors flow matched and install the higher flowing injectors in 7,8.
