Has anyone experienced or know of anyone who has had a sparkplug blow out of their cylinder head and strip the head threads for no apparent reason? Apparently there are 100's of people across the country that this is happening to and Ford is not admitting to any wrong doing. It seems that the #3 sparkplug hole on the passenger side only has 4 threads making it susceptible to thread stripping, even with the originally installed sparkplugs. Was curious to see what people had to say about this problem.
