    If you’re planning to change the spark plugs in your 2008 F-150, follow these steps:

    1. Make sure the engine is cool before starting any work.

    5. Place the socket over the spark plug and turn it counterclockwise to loosen and remove the old spark plug.
    6. Inspect the spark plug for any signs of damage or wear. If necessary, replace it with a new one of the same size and type.
    7. Apply a small amount of anti-seize compound to the threads of the new spark plug.
    8. Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand to avoid cross-threading.
    9. Tighten the spark plug using the socket and ratchet, turning it clockwise until it is snug. Be careful not to overtighten.
    10. Reattach the spark plug wire by pushing the boot firmly onto the new spark plug until it clicks into place.
