Spark Plugs for 2000 Ford E-350 SD Triton 5.4L V8 2V

Gene in NE, I read the articles in the Consumer Affairs you listed. As an owner of a 2008 Ford V-10 Triton, I was aware of such problems, but so far, with 110,000, I have not experienced such problems. Have I been lucky, or should I anticipate problems in the future? Should I go ahead and start changing the coils and the plugs now? But since it appears to be a problem with the plug threads, could the same thing happen even with new plugs? Thx.
