How often should you change spark plug?

Motion Pro plug wrench for the YZF. Nice little tool; rubber lined socket, comes with its own swivel extension, and the extension gives you three different options as to what to use to drive it with.

Local Bike Shop item.

Thanks.

Most hardware stores will also sell a socket (16mm) that will work nicely on a spark plug. At least that is where I found mine.
