If it looks like something is hitting it (side, bent electrode smashed down against center electrode), the the “reach” is too long, and you need a shorter plug length.

Answer by vtwin_doc
If something is “smashing” your spark plugs, there are only 2 things that would cause this….
1 you have the wrong length spark plug (too long)
OR
2 You have a bad rod bearing and/or wrist pin bushing, allowing the piston to travel too far upward and hit the plug
