What could have happened? H12 Plug issue-Dell?

Posted by bfisherman11 on September 29, 2013 at 18:57:43 from (173.20.195.122):

I bought Champion H12"s and set the gap to .025 as recommended on this board. I am no novice but this was strange.

I removed my old plugs (AL82=Motorcraft). I put in the H12"s and bam it would not start. Eventually it did but something was wrong.

I pulled the H12"s and the ground wire/side electrode was flattened out........ It looked like something hit all 4 and flattened them out. I should have compared them at that point to the AL82"s but I was so shocked I just put the AL82s back in. As I suspected the old 1941 9N fired up and ran well.

So what could have done this? I have never seen anything like this ever. Oh, I did have the gaskets on so that if anything would have kept the plugs further out. Also I did not over tighten.

Thanks,

Bill
