I was wondering if anyone else has had this experience with their spark plugs...... The insulator is complete loose and slides up and down the Center Electrode and makes contact with the Ground Electrode. If you hold the plug with the threads pointing up, everything looks fine. Turn it with threads down and insulator slides down and contacts the Ground Electrode. These are brand new plugs right out of the box. Maybe I was just unlucky, but have learned a good lesson to really look the plug over before installing.
