Standard Ignition MAS0504 Mass Air Flow Sensor

Mass Air Flow Sensor for Buick and Chevrolet

The Standard Ignition MAS0504 mass air flow sensor delivers accurate airflow readings to the engine control unit so fuel delivery can stay properly balanced under changing engine loads. This new, sensor-only replacement is built for direct bolt-on installation and is a strong match for drivers searching for a Buick Cascada mass air flow sensor, Buick Encore MAF sensor, or 2016 Chevrolet Cruze airflow sensor replacement.

Key Features

• New, never remanufactured construction
• Computer-tested for accurate airflow output under hard engine conditions
• Proprietary sensing elements maintain consistent readings across a wide ambient temperature range
• Bolt-on attachment method with one oval female connector
• ABS plastic housing design, sensor only
• 8-terminal blade-style connection layout

Detailed Description

Standard Ignition MAS0504 is a mass air flow sensor engineered to provide the ECU with precise intake airflow data so the engine can calculate the correct air/fuel ratio. The unit is manufactured new rather than remanufactured, helping eliminate contamination concerns associated with reused components. Its sensing elements are calibrated for stable output in varying temperatures, and each unit is computer-tested to verify signal accuracy before use. This part cross-references Bosch 0280218433 for the same application.

Fits 2016-2019 Buick Cascada, N/A. Fits 2016-2019 Buick Encore, N/A. Fits 2016 Chevrolet Cruze, N/A. The MAS0504 is a direct-fit option for these applications when replacing a failing airflow sensor.

What It Helps Solve

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response from incorrect fuel metering
• Check engine light conditions related to mass air flow sensor performance
• Lean or rich running concerns tied to faulty intake air measurement
• Driveability issues during acceleration or changing engine load

Installation Notes and Tips

Verify the connector shape, terminal count, and bolt-on mounting style before installation. Inspect the intake tract for leaks, contamination, or damaged wiring that could affect sensor readings. Because this is a sensor-only replacement, reuse the existing housing if the application requires it. Confirm fitment against the vehicle’s original part number and connector layout before final assembly.

Quality Assurance

Standard Ignition manufactures this MAS0504 sensor to strict quality standards and computer-tests each unit to confirm accurate airflow signal output. The new-only design supports consistent performance without remanufactured debris concerns.
