The major quality control spills that I have heard about seem to have happened within the last ten years. There seem to have been two issues. One was a problem with the insulators fouling quickly, and another was a problem with the insulators breaking inside the plug and then sliding down to touch the ground electrode. These problems were reported to happen to almost all of the plugs in a set of new plugs, not just to one in a set. If you have plugs with these problems, then you will know it very quickly. However, most of the complaints that I have either heard about or read are consistency problems, such as poor performance/life of one plug in a set or badly bent/gapped electrodes. I would suggest that you just use what you have, and only junk them if you have major problems. [Reply]   [No Email]
