Mass Airflow Sensor with Intake Air Temperature Sensor Replacement for Chevrolet Tahoe - 2WD 2007

Important: Use care when handling the mass air flow (MAF)/intake air temperature (IAT) sensor. Do not dent, puncture, or otherwise damage the honeycell located at the air inlet end of the MAF/IAT. Do not touch the sensing elements or allow anything including cleaning solvents and lubricants to come in contact with them. Use a small amount of a non-silicone based lubricant, on the air duct only, to aid in installation.
