*In case of idling during idling or a car that is thin under load / often running under idling or lean / rough idling or stalling, the MAF sensor needs to be replaced. MAF, also call top-quality air flow sensor, is a sensor used to determine the mass flow of air entering a fuel-injected internal combustion engine. Before installing the MAF, sure clean the air box and replace the air filter, otherwise "Code and Check Engine Light" may always be displayed even if the MAF is replaced with a new one. *REPLACE PART - Replace For 5WK9600Z, 5WK9617, 213-3360, 2133360, 207084, 228299, 13221702078, 74-10043, 5WK9600, 13621703275, AA17410043, AUS31-3013, AU313013, NEC XTP410043. *FIT THE FOLLOWING VEHICLE - Mass Air Flow Sensor fit for 1998-1999 Replacement For BMW 323i 2.5L L6; 1998-1999 Replacement For BMW 323is 2.5L L6; 1996-1999 Replacement For BMW 328i 2.8L L6; 1996-1999 Replacement For BMW 328is 2.8L L6; 1997-1998 Replacement For BMW 528i 2.8L L6; 1996-1999 Replacement For BMW M3 3.2L L6; 1997 Replacement For BMW Z3 Roadster 2.8L L6.
