Q: How to remove and install the air filter housing and components on Nissan Murano?A: Remove the left and right radiator top covers. Remove the large plastic air inlet duct. Disconnect the wiring from the Mass Airflow/Intake Air Temperature (MAF/IAT) sensor. Disconnect the PCV hose. Loosen the air intake duct clamp and disconnect the electrical connector from the MAF/IAT sensor. Remove the lid of the air filter box with the duct and MAF/IAT sensor attached. Remove the air filter element. Remove the mounting bolt from the top of the air filter box, then pull the box from the grommets at the bottom. The lower box is secured by this bolt and two lower nuts. Installation is the reverse of removal.
