@durox no.Thats not a primary function.
-
@njipods Bad example: Yes but think why pc has also coolant? It would break if it doesn't have it. Same thing with the spark plug! It would heat up if it hadn't technic for removing the heat. It would break also if it removes heat too much, then it would be covered with coal.. And guess what? It would break again.

u wonder how diesel engines keep cool then, because they dont have spark plugs...
-
@huuko07 yes thats true but its not its job! its jobs to make sparks thats why its called a spark plug
its like saying computers job is to surf the internet and heat the room. sure my pc heats my room but thats not why i built it!
-
@njipods He's right, and you're right. The sparkplug warms up also, and if it doesn't remove it's heat, it breaks.

Actually you are wrong. A spark plug's role in heat dissipation of the motor is infintisimal, most plugs are buried in the head with no exposure 2 air for cooling. Its heat dissipation rate is to cool itself, NOT the motor. It gets heat from conducting electricity and from combustion. If you want to know facts about this don't take advice from a punk behind the auto part counter or a hi school whizkid, contact the engineers at one of the spark plug companies or a race team turning chief.

Looks like an air cooled motor to me... haha... Now who's the idiot?

@njipods wrong again!?! ;]
Part of your spark plug’s responsibilities,in addition to firing a spark, is to remove heat from the combustion chamber. This is accomplished by channeling the heat through the insulator material and metal housing. From there, the heat is transferred to the cylinder head where the engine cooling system can go to work. A spark plug’s heat range is its ability to dissipate heat. The “colder” the plug, the more heat it can channel out of the combustion chamber.

isn't the transfer of heat what the coolant is for? This dude is an idiot
