How do you change spark plugs on a vw polo vivo?

To change the spark plugs on a VW Polo Vivo, first, ensure the engine is cool and disconnect the negative battery terminal for safety. Remove the ignition coil or spark plug cover to access the spark plugs, then use a spark plug socket and ratchet to unscrew and remove the old plugs.
