Keep air-to-fuel metering accurate on your heavy-duty truck with the Standard Ignition Mass Air Flow Sensor (MAS0529). It installs as a direct-fit replacement for the 2019-2024 RAM 2500 and 2019-2024 RAM 3500.
- Core job: measures the mass of air entering the engine and reports it to the powertrain control module, which uses that reading to calculate how much fuel to inject.
- Signs this sensor may need replacing: rough idle, hesitation or a stumble on acceleration, stalling, reduced fuel economy, or an illuminated check engine light. Diagnose the cause first — if the air flow sensor is the source, this replaces it.
- Direct-fit application: serves as a direct-fit replacement for the original sensor on the listed RAM 2500 and 3500 trucks.
