What causes spark plugs to go bad fast?

Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.

What kills a spark plug?

If the tip temperature is higher than 850°C the spark plug will overheat which may cause the ceramic around the centre electrode to blister and the electrodes to melt. This may lead to pre-ignition/detonation and expensive engine damage.

How quick can a spark plug go bad?

Luckily, spark plugs don't wear out very quickly. You can typically get 80,000 miles on them before they need replacing.
