Give the ECU an accurate read on incoming air with the Beck/Arnley Mass Air Flow Sensor 158-1820. This sensor measures the mass of air entering the engine and reports it to the ECU, which uses that signal to help set fuel delivery. It's an application-specific, direct replacement across a wide range of Acura and Honda models — including the 2023-2024 Acura Integra (L4-1.5L), 2019-2024 Acura RDX (L4-2.0L), 2018-2024 Honda Accord (L4-1.5L, L4-2.0L), 2016-2024 Honda Civic (L4-2.0L), and 2017-2024 Honda CR-V (L4-1.5L). See the Buyer's Guide tab for the full list of years, models, and engine codes.
- Matches OE form, fit, and function: engineered as a direct replacement for foreign-nameplate applications.
- Application specific: check the catalog data and confirm fit for your vehicle before ordering.
- Install note: a relearn or reset procedure may be required — consult the vehicle service manual.
- Diagnose first: professional diagnostics are recommended; also check the intake for vacuum leaks, a dirty air filter, and damaged wiring or connectors.
If a failed mass air flow sensor is the cause of symptoms like rough idle, hesitation, stalling, or reduced fuel economy, this replaces it. Country of origin: Japan.
