    IMPORTANT: Take care when handling the mass air flow/intake air temperature (MAF/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. Do not allow anything, including cleaning solvents and lubricants, to come in contact with the sensing elements. Use a small amount of a non-silicone based lubricant on the air duct only, to aid in the installation. Do not drop or roughly handle the MAF/IAT sensor.
  2. Remove the air intake duct clamps from the MAF/IAT sensor and the throttle body.
