OSKYUO Mass Air Flow Sensor AFH70M-41B is a direct-fit replacement MAF meter engineered to restore accurate airflow measurement for compatible Honda and Acura engines.

This OSKYUO MAF sensor (also referenced as AFH70M-41B and cross-referenced to OEM numbers like 37980‑RNA‑A01, 37980‑RAD‑L11 and 37980‑RV0‑A01) provides the airflow data the engine control unit needs to calculate fuel delivery and ignition timing. Built from durable plastics and designed to match factory mounting and electrical connections, this unit fits a wide range of Honda and Acura models from the early 2000s through the 2020s. The following information helps you confirm fitment, understand performance attributes, and evaluate installation and warranty details.

How do I confirm this MAF sensor fits my vehicle?

Begin by checking your vehicle's year, make and model against the listed compatible vehicles and by comparing your existing sensor's part number to the cross-reference list. Visual match of the connector, mounting points, and sensor bore diameter helps ensure a correct fit before purchase.

• Compare OEM numbers: AFH70M-41B, 37980‑RNA‑A01, 37980‑RAD‑L11, 37980‑RV0‑A01, etc.
• Fits many Honda models 2003–2021 and Acura models 2007–2022 (see product compatibility)
• Verify connector pin configuration and mounting flange shape

What improvements can I expect after installing this MAF meter?

This replacement measures incoming air flow and sends those signals to the engine control unit so fuel and ignition adjustments can be calculated. Installing a properly functioning MAF sensor can help the ECU return to intended operating strategy when the original sensor was failing or out of spec.

• Restores accurate airflow readings to the ECU for better engine control
• Reduces drivability issues caused by erratic MAF signals
• Designed to meet OEM mounting and electrical interface for direct fit

Is installation difficult, and what tools or steps are required?

Installation is straightforward for most DIYers: remove the intake duct to access the old sensor, unplug the electrical connector, unbolt the sensor, and install the new unit in reverse. No specialized calibration is typically required, but clearing codes after replacement may be needed depending on your vehicle.

• Simple removal and replacement—bolt-on design with matching connector
• Basic hand tools usually suffice (screwdriver, socket set)
• Clear engine codes or disconnect battery if advised by your repair manual
