    Just curious. Is it better to change plugs with a warm or cold engine?

    cold it hurts less
    I've usually done it on cold engines it's just easier. I would think you would want the plugs and engine about the same temp to get true torque values

    Cold. If hot aluminum and steel don't expand at the same rate.
