Delphi Mass Air Flow Sensor P/N:AF10174
Delphi AF10442 mass air flow sensor for the 2007-2013 Mazda 3 4-cylinder 2.3L and other vehicles measures the air entering the engine. It is calibrated and tested to match the OE part.
Rough idle, hesitation, poor fuel economy or a check engine light can come from a failing mass air flow sensor, but those signs alone do not prove it; a vacuum leak in the intake is another common source. If the sensor is the cause, this probe replaces it.
The 2007-2013 Mazda 3 4-cylinder 2.3L, the 2004-2008 Subaru Forester H4 2.5L and the 2003-2008 Subaru Outback H6 3.0L all take this mass air flow sensor, one each, and so do many other vehicles. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
