That is literally the first NGK plug I have ever seen do that.

It might be a issue with that particular plug number but If you do that with a NGK automotive plug I think you dont know your own strength.


As I said, getting into an ATV to change a plug is not somthing you can use any real tools on...And it was just a short handled wrench...And it was not even tight yet...Then I had to figure out hot to get that portion out of the cylinder.
