Crazy. I just today, finished fixing my 4runner, because whoeverput in the previous plugs, crossthreaded em, and the plug broke because it was so tight. I had to pull the head, and take it to a machine shop, and have em drill it, and use a time sert, not a heli-coil. That sucked sooo bad. I hope this works for you. I wouldve gone that route, but The plug broke. Good luck.
