Walker 245-1430 Mass Air Flow Sensor

Walker Sensor Only Mass Air Flow Sensor

Restore accurate airflow measurement with the Walker Sensor Only Mass Air Flow Sensor, part number 245-1430. This black, 5-terminal MAF sensor uses a male oblong connector and 2 mounting holes for a direct sensor-only replacement on select Subaru applications.

Fits 2013-2020 Subaru BRZ and 2016 Subaru Crosstrek, sensor only. If you are replacing a Subaru BRZ MAF sensor or a Subaru Crosstrek mass air flow sensor, 245-1430 is built for the specified applications.

Key Features

• Sensor-only design for a faster, more economical replacement
• Black housing color with 1 connector and 5 terminals
• Male connector with oblong shape for the listed applications
• 2 mounting holes for secure installation
• 100% new, never remanufactured
• Programmed and tested for fit, form, and function before release
• Custom tuned flow characteristics for the full flow spectrum
• Made by Walker Products, an ISO 9001 and IATF 16949 certified manufacturer

Product Details

Walker Sensor Only line parts are offered as replacement sensors without the housing assembly. For applications that call for sensor-only service, this approach keeps the original housing in place while replacing the airflow sensing element. Walker engineers calibrate these MAF sensors to meet OE long-term fuel trim targets, and each unit is production tested and verified with on-vehicle testing. Part number 245-1430 is also cross-referenced to 22680AA400 for the same application.

Common Problems This Part Can Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to mass air flow sensor performance
• Poor fuel trim correction from a failing MAF sensor
• Driveability issues after contamination or sensor wear

Installation Notes and Tips

Before installation, inspect the connector, air tube area, and surrounding intake components for dirt, oil, or damage. Handle the sensor carefully to avoid contaminating the sensing element, and confirm the connector shape, terminal count, and mounting points match the original part. For Subaru BRZ and Subaru Crosstrek service, verify the vehicle uses the sensor-only configuration shown in the fitment data. Part number 245-1430 should be installed on the listed applications only.
