Spectra MA500 Mass Air Flow Sensor

Spectra MA500 Mass Air Flow Sensor

The Spectra MA500 mass air flow sensor is a standard replacement part for vehicles that need accurate intake air measurement and stable engine management. It uses a programmable ceramic circuit board with a premium silicon coating to help protect the sensor from under-hood heat swings and road vibration.

Compatible With Audi Q3, Volkswagen Passat, Audi A5 Quattro, Audi A5 Sportback, Audi A6 Quattro, Audi A7 Sportback, Volkswagen Arteon, Volkswagen Tiguan, Audi A3, Audi A3 Quattro, Audi A4, Audi S3, Volkswagen Beetle, and Volkswagen Vento applications.

• Standard replacement mass air flow sensor
• Black plastic housing with housing included
• Oval 1-connector design with 4 blade terminals
• 70 mm inlet connection diameter and 70 mm outlet connection diameter
• Programmable ceramic circuit board with silicon coating for thermal and vibration resistance
• Uses platinum resistance thermometer sensor technology for faster signal response and consistent readings

Detailed Product Overview

The MA500 is built for direct air metering in modern fuel-injected engines, helping the engine control system calculate airflow more precisely. Its electronic design focuses on signal consistency, while the coated ceramic board adds protection in demanding operating conditions. This part cross-references Delphi AF10656 for the same application.

Use the Spectra MA500 when servicing Audi and Volkswagen models that call for a replacement mass air flow sensor, including 2016-2024 Audi Q3, 2018-2022 Volkswagen Passat, and 2018-2021 Volkswagen Tiguan applications. The part number MA500 is also a useful reference when matching OE-style replacement sensors for these platforms.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response from incorrect air metering
• Check engine light concerns related to mass air flow sensor performance
• Fuel trim issues tied to inconsistent intake air data
• Driveability problems after sensor contamination or electrical wear

Installation Notes and Tips

Confirm connector shape, terminal count, and inlet/outlet diameter before installation. Inspect the intake tube, electrical connector, and surrounding air ducting for damage or contamination, and clear any stored diagnostic trouble codes after replacement. Verify fitment by year, make, and model before ordering; MA500 is listed for multiple Audi and Volkswagen applications, including Audi A3, Audi A4, Audi A5 Sportback, and Volkswagen Arteon.

Quality Assurance

Spectra builds this sensor with a coated ceramic circuit board and platinum resistance thermometer sensor elements to support stable operation in heat and vibration-prone engine bays. The MA500 is a standard replacement part engineered for consistent airflow signal output across the listed Audi and Volkswagen fitments.
