Installation Procedure

    Notice: Do not damage the MAF sensor screen. A damaged screen could restrict airflow and lead to a driveability concern.

    Important: The MAF sensor must be mounted with the air flow direction arrow (located on top of the MAF sensor) pointing with air flow towards the throttle body. Ensure that the MAF sensor locating tabs and the locating slots of the IA ducts line up before connecting the MAF sensor and IA ducts.
