Product Details

Walker Products builds this mass air flow sensor as part of its Complete Assembly line, which is designed for applications where replacing the sensor and housing together is preferred. The brand’s MAF program uses OEM-quality components, custom engineered circuit boards, and production testing to verify fit, form, and function. Walker also validates calibrations with on-vehicle testing to help maintain OE long-term fuel trim performance. Part number 245-1580 is a direct replacement option for vehicles such as the 2015-2019 Hyundai Sonata, 2017-2020 Kia Optima, 2018-2024 Kia Forte, 2020-2024 Kia Forte5, 2019-2020 Hyundai Elantra, and 2019-2024 Hyundai Nexo.

This part cross-references Hyundai/Kia OE number 281642E000 and Standard Ignition MAS0464 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Check engine lights related to mass air flow sensor faults
• Hesitation or poor throttle response
• Fuel trim issues from incorrect air measurement
• Driveability problems tied to contaminated or worn sensor assemblies

Installation Notes

Before installation, confirm the connector shape, terminal count, and mounting style match the original unit. Because this is a complete assembly, inspect the intake tract and connector area for dirt or contamination before fitting the new sensor. Avoid touching the sensing element and make sure the clamp mount seats securely during installation.
