Prenco 4M-1037 Mass Air Flow Sensor
Mass Air Flow Sensor for Select Nissan and Subaru
This Prenco mass air flow sensor, part number 4M-1037, is built for select Infiniti, Nissan, and Subaru applications that use a housing-mounted MAF sensor. It features a black housing, a rectangular female connector, and 5 blade terminals for a direct-fit electrical connection.
Key Features
- Mass air flow sensor for emission control and engine air measurement
- Black sensor body with rectangular connector shape
- Female connector with 5 blade terminals
- 1 connector design for a clean OE-style interface
- Mounting hardware and mounting bracket not included
- Part number 4M-1037 for easy catalog matching
Detailed Description
Prenco 4M-1037 is a replacement mass air flow sensor used to measure incoming air so the engine control system can calculate fuel delivery more accurately. It is listed for 1999 Subaru Forester, 1999 Subaru Impreza, 1999 Subaru Legacy, 2000-2001 Infiniti I30, 2000-2002 Infiniti G20, and 2000-2001 Nissan Sentra, all with housing. This part cross-references Beck/Arnley 158-0734 and Standard Ignition MAS0144 for the same application. The 4M-1037 is a practical choice when servicing drivability and air metering concerns on these Infiniti, Nissan, and Subaru platforms.
What It Helps Address
- Rough idle caused by inaccurate airflow readings
- Hesitation during acceleration
- Lean or rich fuel trim conditions tied to airflow signal errors
- Check engine light concerns related to the mass air flow circuit
- Poor throttle response from a failing air metering sensor
Installation Notes and Tips
Verify the connector style, terminal count, and housing-mounted configuration before installation. Inspect the intake tract for dirt, oil contamination, or air leaks that can affect sensor readings. Confirm the vehicle application by year, make, and model before ordering, especially for 2000-2002 Infiniti G20, 2000-2001 Infiniti I30, 2000-2001 Nissan Sentra, and 1999 Subaru Forester, Impreza, or Legacy.
Quality Assurance
Prenco replacement parts are cataloged for direct application matching and OE-style fitment verification. Part number 4M-1037 is listed against confirmed vehicle applications and cross-reference numbers to support accurate selection.
