To change the spark plugs in a 2008 Highlander Sport, first, ensure the engine is cool and disconnect the negative battery cable. Remove the engine cover if necessary, then locate the spark plug wires or coils and carefully disconnect them. Use a spark plug socket and ratchet to remove the old spark plugs, then install the new plugs, ensuring they are properly gapped and torqued to the manufacturer’s specifications. Reconnect the spark plug wires or coils, and reattach the battery cable.
