What does it mean to run a colder plug. I understand part numbers but what does it do?

gsr x civic

pretty much the higher the step number the colder it is, and the colder it is, the faster it'll transfer heat to the head, resulting in prevention of detonation. i don't know the theory going behind "too cold" or whatever, nor do i know the coldest step.

you dont really need them unless you're boosted. i'd go with a 7 or 8 step depending on the setup. a .28 gap would suffice, although a .32 is ideal ( correct if i'm wrong. i'm only going by memory )

come back with more questions if you have any

It means the colder the plug, the more heat it will transfer into the head/engine and away from the tip of the spark plug.

ok i see. so when u get a colder plug it just transfer the heat to the head faster..hince..a colder plug.

gsr x civic

yes, because heat isn't retained in the combustion chamber as long.

i think only NGK does it higher=colder. Champion makes some hella cold range race plugs that work in hondas also
