- Meters intake air: measures incoming air mass and sends the signal the engine computer needs to set fuel delivery.
- Direct-fit replacement: a direct-fit replacement for the listed applications.
- Signs it may need replacing: rough idle, hesitation, stalling, poor fuel economy, or an illuminated check engine light — if a faulty MAF sensor is the cause, this replaces it. Diagnose the cause before replacing.
