How often do you change your plugs? I usually change mine every year but my mates only change them every other year. I do notice that when removed they don't look that bad

Change them regularly.
My plugs were worn down at 11,000 km's. misfiring and everything.

Suprizing you guys run your plugs for even longer. The gaps must be huge.
