    Step-by-Step Guide

    If you’re ready to change the spark plugs in your 2015 Mustang EcoBoost, follow these steps:

    1. Ensure the engine is cool before starting any work.
    2. Locate the spark plugs on the engine. They are typically found on the top of the engine, connected to the ignition coils.
    3. Remove the ignition coil by gently pulling it straight up. Be careful not to damage any wires connected to it.
    4. Once the ignition coil is removed, you will see the spark plug sitting inside the cylinder head.
    5. Using the appropriate spark plug socket size (5/8″ or 16mm), attach it to a ratchet or extension.
    6. Place the socket over the spark plug and turn it counterclockwise to loosen and remove the spark plug from the cylinder head.
    7. Inspect the old spark plug for any signs of damage or wear. If necessary, replace it with a new one of the same type and gap size.
    8. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the future.
    9. Insert the new spark plug into the cylinder head and hand-tighten it until snug.
    10. Using the spark plug socket and ratchet, tighten the spark plug an additional 1/16 to 1/8 of a turn.
    11. Reinstall the ignition coil by pushing it back into place until it clicks securely.
    12. Repeat the process for each spark plug in the engine.
