Removal Procedure

Important: Take care when handling the MAF. Do not dent, puncture, or otherwise damage the Honeycell located at the air inlet end of the MAF. 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.
