Key Features

• Hot-wire sensor design for precise airflow measurement
• Specific-fit replacement for direct application matching
• Plastic housing with black finish
• 4-pin rectangular connector with female plug interface
• Pipe-neck mounting with 3.15 in. / 80 mm inlet connection diameter
• 12V electrical specification
• Standard replacement grade for OE-style service

Detailed Description

HELLA 009149441 is a mass air flow sensor built to report incoming air volume accurately so the engine control system can calculate fuel delivery correctly. That matters on turbocharged and naturally aspirated engines alike, especially when drivability symptoms point to incorrect airflow data. This sensor uses a hot-wire design, includes the housing, and is configured for a specific fit with a single rectangular connector and four terminals.

Vehicle coverage includes 2015-2016 Audi A3, 2013-2015 Volkswagen Beetle, 2015 Volkswagen Golf, 2015 Volkswagen Golf SportWagen, 2015 Volkswagen Jetta, and 2012-2015 Volkswagen Passat. If you are searching for a 2015 Volkswagen Golf MAF sensor, a 2015 Volkswagen Jetta mass air flow sensor, or a 2015-2016 Audi A3 airflow sensor replacement, this part number 009149441 matches the listed pipe-neck and 4-pin configuration.

This part cross-references Delphi AF10397 and Walker Products 245-1106 for the same application.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or delayed throttle response
• Reduced fuel economy from incorrect air metering
• Check engine light conditions related to MAF sensor performance
• Driveability issues after a failing or contaminated airflow sensor
