A friend of mine was removing a sparkplug and noticed it was unusually tight. So when he finally got it out it, the plug was rusted and had some threads (about 3, on one side of the plug, one thread, and on the opposite side, 2) removed along with it. Is there any solution to fixing this? Has anyone experienced this? What did you do if you experienced this? I wanna help him out and want to find out as much as possible to fixing this as I am going to ask other people for their options aswell. Thanks for your help guys

i would say try and put another spark plug back in and see if it goes in easy
