Bosch Mass Air Flow Sensor MAF - Focus Mk2 ST225
This item is an OEM replacement part for the 2.5 turbocharged engines and manufactured by Bosch, fitting the Focus ST Mk2
The job of the Mass Air Flow sensor is to detect the volume, temperature and density of the air passing through it. This information is then relayed to the ecu so the fuel trims can be commanded to make the correct mixture for the exact volume of air being received. When the MAF is faulty, dirty or faulty it will not usually see the correct air volume and the car will either over or under fuel and can cause a lumpy idle and in certain cases an esp fault can appear on the dashboard.
This is the insert only without the housing so you will need a 5 pointed Torx security bit to undo the 2 screws holding it in.
Genuine Bosch part, alot cheaper than full housing from Ford
