Want to replace the spark plugs on a Mercedes CLA? Open the hood, lift it, and let's see how to do it. Disconnect the battery terminals, remove the soundproofing cover from the engine, and use a screwdriver or pliers to remove the coils from the engine head; then unscrew the spark plugs with a socket wrench and pull them out of the head.

Take the new spark plugs and guide them with the socket extension into the engine head, tighten them, and connect the ignition coils to each spark plug.

Close the hood and test the vehicle's proper operation. Start the vehicle and perform a functionality test.
