    Step-by-Step Guide

    If you’re ready to replace the spark plugs in your MK4 Golf, follow these steps:

    1. Make sure the engine is cool before starting any work.
    2. Locate the spark plugs. In the MK4 Golf, they are typically found on top of the engine, connected to the ignition coils.
    3. Remove the spark plug wire or ignition coil from the first spark plug by gently pulling it straight off.
    4. Using the appropriate spark plug socket size from the chart above, attach it to a ratchet or extension.
    5. Place the socket over the spark plug and turn it counterclockwise to loosen and remove the spark plug.
    6. 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.
    7. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the future.
    8. Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand. Make sure not to cross-thread it.
    9. Tighten the spark plug using the socket and ratchet, turning it clockwise until it is snug. Be careful not to overtighten.
    10. If you removed an ignition coil, reattach it to the spark plug. If you removed a spark plug wire, push it back onto the spark plug until it clicks into place.
    11. Repeat the above steps for each spark plug, one at a time, until all of them have been replaced.
