To change the spark plugs on a 2003 Lincoln LS with a V6 engine, first, disconnect the negative battery cable for safety. Remove the engine cover if necessary, then locate the spark plug wires or ignition coils and carefully disconnect them. Use a spark plug socket and ratchet to remove the old spark plugs, and install the new ones, ensuring they are properly gapped according to specifications. Reconnect the ignition components and battery cable, and start the engine to verify everything is working correctly.
