Hello, The plugs "look OK" to me, but I have questions and comments. 1) The gap seems large. I'd guess they're around .070". I know there were high energy systems which had larger gaps, but not that big. 2) Are the insulators discolored or are they merely a bit greasy and have dirt on them? By the look of the body of those plugs, it took time to rack up those 50,000 miles. Kira
