Spectra MA128 Mass Air Flow Sensor

Mass Air Flow Sensor Overview

The Spectra MA128 mass air flow sensor is built for direct replacement applications that require accurate airflow signal delivery and stable operation under hood heat and vibration. It is a fitment-based solution for select Audi and Volkswagen models with an integrated housing.

Key Features

• Programmable ceramic circuit board with premium silicon coating for added protection.
• Fast signal response for consistent airflow measurement.
• All-platinum resistance thermometer sensors for precise sensing performance.
• Integrated housing application for select import vehicle fitments.

Detailed Description

The Spectra MA128 is a mass air flow sensor engineered for vehicles that rely on accurate intake air measurement for proper engine management. Its circuit board uses a ceramic design with premium silicon coating to help resist temperature swings and vibration, while the platinum resistance thermometer sensors support responsive signal output. This part is a direct-fit option for select Audi TT, Audi A4, Audi A4 Quattro, Audi TT Quattro, Volkswagen Golf, Volkswagen Jetta, Volkswagen Passat, and Volkswagen Clasico applications that use an integrated housing. The MA128 part number is also useful when cross-checking replacement needs against OE-style references.

What It Helps Address

• Rough idle caused by inaccurate airflow readings.
• Hesitation during acceleration from unstable sensor output.
• Poor fuel control related to incorrect air measurement.
• Check engine light conditions tied to mass air flow sensor faults.

Installation Notes and Tips

Confirm the vehicle uses the integrated housing configuration shown in the fitment data before ordering. Match the connector style and housing layout to the original unit, and verify the MA128 part number against the existing sensor when comparing replacements.
