spark plugs overheating

[Cesarlcase]

could the wrong type of spark plug ( a stock spark plug on a car pushing say 25lbs of boost) before destroying the motor cause the car to overheat? please explain. thanks

I can make this work; if the stock plugs are too hot for your tune, it could cause detonation. Detonation could cause head gasket failure. Head gasket failure could cause overheating before destroying the engine.

Is that the senario you needed drawn out? This would be based on the assumtion that you are beating a modded car without monitoring the engine. Most people would stop boosting and fix the problem at the first sign of knock.

well I just always thought a hotter plug would literally impact engine temps. that's not the case correct?

I wouldn't think it would make an appreciable difference.

Also a spark plugs heat range basicaly tells you how effectively the plug rmoves heat to the block via the plugs insulator. But not all companies use the same numbering scale, i.e. NGK's, the higher the number the colder the plug, on another plug it could be the exact opposite.
