CAUTION: 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 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. DO NOT drop or roughly handle the MAF/IAT sensor.

Disconnect the MAF/IAT sensor electrical connector. Remove the air cleaner assembly. Loosen the clamp securing the MAF/IAT sensor to the air cleaner duct. Remove the MAF/IAT sensor bolts from the air cleaner assembly. Remove the MAF/IAT from the air cleaner. To install, reverse removal procedure. The embossed arrow on the MAF/IAT sensor indicates the proper air flow direction. The arrow must point toward the engine. Tighten fasteners to specification. See TORQUE SPECIFICATIONS .
