4.6L 2V Blowing Spark Plug

[DRVANGRY]

So I have been around Mustangs for a long time and have own a number of them. I have had my 2002 GT convertible for 9 years now and have never heard anyone talk about Blowing a spark plug. Literally it Blows out of the threads and goes straight thru the Coil. Luckily it stopped for me and didn't cause very much damage. Apparently this is more common then I could have ever imagined. Not to worry though, you can have it repaired without breaking the bank. Has anyone else had this happen?

Super common, apparently Ford thought that more than three threads to hold a spark plug in was way to much, who knew?

Same problem carried over to the 4.6 and 5.4 in the pick up trucks.

^Then Ford reversed the entire issue, lol.
