Mass Air Flow (MAF) Sensor — Accurate airflow measurement to support reliable engine performance Key benefits Restores accurate air intake data so the engine control unit can better manage fuel and ignition, helping stabilize idle, throttle response, and fuel use. Direct-fit replacement for specified models, reducing diagnostic time and installation adjustments. Durable construction and consistent sensor output for dependable performance under normal driving conditions. What it does Measures the amount of air entering the engine (mass air flow) and sends that information to the vehicle’s engine control system, supporting correct fuel metering and engine operation. Compatibility MAZDA: 3, 6, CX-7 with the 2.3 MPS DiSi engine, model years 2005–2009 (suitable for turbo models). SUBARU: compatible with specified Subaru vehicles that use this MAF sensor design. JAGUAR: specifically designed replacement with part number 2W93 12B579 AC. Replacement part reference: can replace MB197400 3031. Key attributes Function: Mass air flow sensing for accurate engine air measurement. Compatibility: Fits the listed Mazda 2.3 MPS DiSi (2005–2009) turbo models, select Subaru applications, and Jaguar part 2W93 12B579 AC replacements. Performance: Provides stable, repeatable airflow readings to support correct fuel delivery and engine control. Fit and installation: Designed as a direct replacement for the stated part numbers to simplify fitment and reduce installation time. Durability: Built for continuous operation in the engine intake environment. Practical use scenarios Replace a failing MAF on a 2006 Mazda 3 2.3 MPS after a check-engine light and inconsistent idle to restore proper airflow readings and improve drivability. Fit the sensor on a Subaru application that uses the same design to correct lean/rich running symptoms caused by an inaccurate mass air flow reading. Swap in the unit for a Jaguar requiring part number 2W93 12B579 AC or replacing MB197400 3031 to maintain correct engine management performance. Notes for buyers Confirm vehicle year, engine type (2.3 MPS DiSi for Mazda turbo models 2005–2009), and part number compatibility before purchasing. Installation should follow standard vehicle service procedures; if unsure, consult a qualified technician. Compatible part references: 2W93 12B579 AC, MB197400 3031.
