Detailed Product Overview

HELLA 358095941 is a direct-fit mass air flow sensor built for vehicles that rely on precise intake air measurement to manage engine performance and emissions. The hot-wire sensing element monitors incoming air volume so the engine control system can calculate the correct fuel delivery. This helps maintain drivability and supports stable operation on 1999-2005 Hyundai Sonata, 2001-2006 Kia Optima, and 2001-2004 Hyundai Santa Fe applications.

This part cross-references Delphi AF10162 and Beck/Arnley 158-0695 for the same application. The HELLA 358095941 is a practical OE-style replacement when the original sensor is no longer reading accurately or the engine management system needs a direct-fit airflow sensor with the correct 5-pin configuration.

Common Problems This Sensor Can Help Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or sluggish throttle response
• Reduced fuel economy from incorrect air-fuel calculation
• Check engine light concerns related to mass air flow sensor performance
• Driveability issues on Hyundai Sonata, Hyundai Santa Fe, and Kia Optima models

Installation Notes and Fitment

Compatible With 1999-2005 Hyundai Sonata, 2001-2006 Kia Optima, and 2001-2004 Hyundai Santa Fe applications with a 5-pin connector and pipe-neck mounting.
