Description:

*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 BMW 5WK9605 13621432356. *FIT THE FOLLOWING VEHICLE - Mass Air Flow Sensor compatible with 1999-2000 BMW 323i 2.5L 1999 BMW 323is 2.5L 2000 BMW 323Ci 2.5L 2001-2003 BMW 325Ci 2.5L 2001-2005 BMW 325i 2.5L 2001-2005 BMW 325xi 2.5L 1999-2000 BMW 328i 2.8L 2000 BMW 328Ci 2.8L 2001-2003 BMW 525i 2.5L 1999-2000 BMW 528i 2.8L 1999-2002 BMW Z3 2.5L 2.8L..
