To replace the ignition coils on a 2000 Infiniti Q45, first ensure the engine is off and cool, then disconnect the negative battery terminal. Remove the intake manifold cover to access the ignition coils, which are located on top of the engine. Unplug the electrical connectors from each coil, remove the mounting bolts, and pull out the old coils. Install the new coils by reversing the removal process, ensuring all connections are secure before reconnecting the battery and testing the ignition.
