I recently changed mine at about 61,000 miles and there wasn't much left of the center electrode, just a tiny tit as compelyc4 mentioned.
Make sure when you are changing your plugs that you wear protection on your arms. I didn't and my arms got all scraped up trying to reach the back plugs. I personally thought it was easier to do the rear ones from below.








I want Pontiac Dad'* engine :P
