If so, what is the purpose of ever changing changing them?
You seem yo be taking an ureasonable position in an effort to disagree with me.

Fact: A spark plugs spark intensity (quality) diminishes over the the life of a plug. This is well documented.
The only thing that can be argued is how much it deteriorates at any given point and at what point an individual chooses to change the plug.
