3. Each spark plug is held in place by a nut. Loosen the nuts using a wrench, then remove the spark plugs by hand.
4. Check the condition of the spark plugs. They should be clean and free of any damage. If they are damaged or worn, they will need to be replaced.
5. To reinstall the spark plugs, screw them back into place by hand. Be careful not to cross-thread the spark plugs. Tighten the nuts using a wrench.
6. Close the hood of your car and you are finished.
