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

 

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.

tee hee. i win :D

 

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

 

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

that is all. in reality, i never won anything. not even a candy bar.

 

been trying to find a step 7 or 8 ngk at the local parts stores like auto zone and advance auto but all i can find is like a 6. i dont think you should have to order them, but what do i know. where do you get yours at?

lol

 

i get mine through advance. the number is bkr7e-11

 

thanks

 

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