Select a socket according to the size of the spark plug nut and turn it counterclockwise to loosen, then use a magnetic rod to extract the spark plug; 3. Use the magnetic rod to hold the new spark plug and place it into the hole, then follow the reverse steps above for installation. When installing the spark plugs, a specialized torque wrench should be used to tighten them.
