Spark plug has no hex sides how do I remove from car?
The spark plug had hex sides to begin with. I am guessing there is something blocking you from seeing them or something in the way. Only other possibility would be if they got rounded and this happens from trying to use the wrong tool. In this case you may need to use a special spark plug removal tool or improvise. You’ll see in the video the use of Quick Steel. Try at your own risk.
