Keep air metering accurate and fuel delivery on target with the Standard Ignition Mass Air Flow Sensor MAS0284. It installs as a direct-fit replacement for the 2003-2005 Mercedes-Benz C230, restoring the signal your engine control module relies on to calculate the correct amount of fuel for the air entering the engine.
- Core job: measures the airflow entering the intake and reports it to the ECU so fueling can be adjusted accordingly.
- Direct-fit replacement: designed to swap in for the listed Mercedes-Benz C230 application.
- Signs it may need replacing: rough or unsteady idle, hesitation, reduced fuel economy, or a check engine light — have the cause diagnosed first, since these symptoms can have other sources.
The mass air flow sensor sits in the intake path and continuously converts incoming airflow into an electrical signal. If a faulty original sensor is the cause of your driveability trouble, replacing it with MAS0284 restores that airflow reading so the ECU can meter fuel correctly.

Which vehicle does MAS0284 fit?
It is a direct-fit replacement for the 2003-2005 Mercedes-Benz C230. Check the Buyer's Guide tab to confirm fitment for your vehicle.
What are the signs my MAF sensor may need replacing?
Possible signs include rough idle, hesitation, poor fuel economy, or a check engine light. These can have other causes, so diagnose the cause before replacing.
What numbers does this part interchange with?
It interchanges with MA1121, 2-14661 (214661), 2710940248, and 271094024880. The manufacturer part number is MAS0284.
Will replacing the sensor fix my rough idle?
If a failed mass air flow sensor is the cause, replacing it with MAS0284 restores the airflow signal. If another component is at fault, further diagnosis may be needed.
