  Q: How to remove and install the air intake duct and air filter housing?

  A: Remove the engine covers. For 3.2L V6 models, loosen the clamp at the Mass Air Flow (MAF) housing and remove the first end of the air intake duct. Remove the mounting fastener that secures the air duct/resonator to the fan shroud. Loosen the clamps at the air ducts and the Throttle Body and remove the air intake ducts from the throttle body. Lift the air intake duct/resonator up out of its mount, disconnect the vacuum lines and harness fasteners, then remove the duct. Installation is the reverse of removal. For all except 3.2L models, disconnect the PCV fresh air hose from the air intake duct. Loosen the clamps at the Air Filter Box and the throttle body and remove the air intake duct. On 5.7L and 6.0L engines, loosen the clamps at the Air Filter Box and the throttle body, then lift the duct up from the Air Filter Box side enough to disconnect the electrical connectors. Remove the duct. Installation is the reverse of removal. For the Air Filter Box, remove the air intake duct. Disconnect the electrical connector from the MAF sensor. Remove the Air Filter Box fastener(s) and maneuver the housing out from the body. Inspect the condition of the Air Filter Box mounting grommets. If they're cracked, torn or deteriorated, replace them. Installation is the reverse of removal.
