I'm well over 10 G's on the OEM spark plugs because well, the Spyder is running just fine. That and I'm a huge fan of if I don't think it's broke don't fix it. That thinking has served me well with the Spyder so far.

I've seen other swap them out as early as a couple thousand miles...but no one has suggested a high end number before replacing the OEM's. I've got the Iridiums just waiting to be slapped in but everything is running so smooth. Can I do any damage if I don't change OEM plugs until either the Spyder starts choking or around 12,000 miles is that going to be an issue?
