Installation Procedure

Important: An improperly installed air cleaner or a distorted or missing intake air duct may cause a diagnostic trouble code (DTC) to set. Ensure that the air cleaner assembly and intake air duct is installed correctly and that there are no kinks or folds in the intake air duct. Debris in the air cleaner assembly or mass air flow (MAF) sensor inlet screen, that may distort air flow can set a DTC.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
