To change the spark plugs in a 2003 Lexus IS300, first, ensure the engine is cool and disconnect the negative battery terminal. Remove the engine cover, then locate the ignition coils on top of the spark plugs; detach the electrical connectors and unscrew the coils. Use a spark plug socket to carefully unscrew and remove the old spark plugs, then install the new ones by hand to avoid cross-threading, ensuring they are torqued to the manufacturer's specifications. Reassemble by reversing the disassembly steps, reconnecting the coils and battery terminal.
