Important: Take care when handling the MAF. Do Not dent, puncture, or otherwise damage the honeywell located at the air inlet end of the MAF. Do Not touch the sensing elements or allow anything (including solvents and lubricants) to come in contact with them. A small amount of GM lubricant (P/N 99855406) may be used on the air duct only to aid in installation. Do Not drop or roughly handle the MAF.
