I think the difference is that one runs 'hotter' than the other ... But what does that actually mean? And how does it affect our engine? Is one better than the other?

Summary -

*Low heat range ( hot plug) long insulator

*High heat range (cold plug) short insulator

*Plug electrode needs to be between 500c - 950c

*Plug below 500c = no self cleaning gets gummed up with carbon - spark leakage, incomplete combustion.

* above 950c = pre ignition - effects performance- plug damage and increased wear.

* Check your plug to determine wether you need hot or cold.

" Various circumstances such as engine conditions and driving conditions are rough measures for choosing a plug. For example, if strenuous driving is continued for a long time using normal plugs, the plug will overheat.
This is why the idea of a regular plug for a regular car doesn't work.
What's important is to inspect the condition of your current plugs, and then choose a plug accordingly."
