To replace the spark plugs on a Nissan Altima, open the hood to access the components inside the engine bay. The spark plugs are located at the top of the engine block and will be accessible after removing the upper covers. You will also need to remove the air filter box: once you have access to the components below, disconnect the connectors attached to the coils, pulling them out and removing the underlying spark plugs using a socket wrench.

You can then install the new spark plugs, reassembling all the removed components.
