Default Copper plug life

I just had my plugs changed today. I had Autolite 104'* with a gap of .050". They were in the motor for 2 years. Now, I know it is recommended that these things get changed once a year because they are 2 ranges colder than stock, and they are copper.

Here is a pic of what one of the plugs looks like:



They didn't look too bad to be honest. The motor still ran good, and I never had misfires. I will get these changed again in one year just to be safe, but I'm suprised these lasted a long time, considering people say to change them more often.

Any thoughts?

They look pretty good. If anything, perhaps one range too cold. I'd expect more tan on the ceramic insulator.

Second thought, if they look that good after two years, keep the heatrange and gap.
