A-Premium Mass Air Flow Sensor for Ford & Mazda — 4-Pin Direct-Fit MAF, ±3% Accuracy

The A-Premium Mass Air Flow Sensor Assembly is a 4-pin bolt-on replacement that measures intake air volume and density for compatible Ford and Mazda engines, restoring accurate fuel metering and drivability.

This direct-fit MAF sensor from A-Premium is built to match factory mounting and electrical connections for a long list of Ford, Mercury and Mazda models. Made from PBT+GF30 and aluminum alloy, the unit uses a rectangular 4-pin connector and four bolt holes for secure installation. With a measurement range up to 9.25 m³/min and ±3% accuracy, it supplies consistent airflow data so the engine control unit (ECU) can calculate appropriate fuel injection under varying conditions.

Which vehicles and engines does this MAF sensor support?

The A-Premium 4-pin MAF is specified to fit many late-1990s and early-2000s Ford, Mercury and Mazda vehicles. Fitment includes multiple Ranger, Escort, Taurus, Sable, Windstar, Aerostar and Mazda 626, B2500 and B3000 applications—check your year and engine size to confirm.

• Ford: Ranger (1995–2001 various 2.3L–3.0L), Escort (1996–2002), Taurus/Sable (1996–1999), Windstar (1995–1997), Aerostar (1996–1997)
• Mazda: 626 (1998–2002 2.0L), B2500 (1998–2001 2.5L), B3000 (1995–2000 3.0L)
• Mercury: Sable (1996–1999 3.0L), Tracer (1996–1999)

How does this sensor affect engine performance and diagnostics?

By reporting intake air volume and density, the MAF gives the ECU the data needed to set fuel injector timing and duration. Replacing a failing or dirty sensor can reduce rough idle, improve throttle response and help clear intermittent fault codes caused by inaccurate airflow readings.

• Provides precise airflow values within ±3% accuracy for stable fuel trims
• Helps eliminate engine hesitation and unstable idle caused by faulty MAF readings
• Allows the ECU to self-correct and clear intermittent diagnostic trouble codes

What are the physical and electrical specs I should know before buying?

The unit is a bolt-on replacement designed around factory-style materials and connector types. Note the rectangular 4-pin plug and four mounting holes; confirm the OEM reference numbers or connector match before ordering.

• Terminal quantity: 4 pin rectangular plug (check compatibility)
• Mounting: 4 bolt holes, bolt-on installation
• Materials: PBT+GF30 polymer housing with aluminum alloy components; color: silver and black
• Electrical: maximum supply 12V; measuring range 0–9.25 m³/min

Is this MAF sensor a reliable replacement and what warranty is included?

A-Premium supplies this part with a one-year unlimited-mileage guarantee to back manufacturing and material integrity. The sensor is manufactured to meet referenced OEM part numbers and undergoes functional design to provide long-term, consistent airflow readings when installed correctly.

• Covered by a one-year unlimited-mileage warranty from A-Premium
• Matches multiple OEM reference numbers for simpler cross-referencing
• Designed to the same connector, mounting pattern and electrical range as originals

Who is this for: This MAF sensor assembly is intended for owners, mechanics and restoration projects needing a direct-fit 4-pin replacement for compatible Ford, Mercury and Mazda models from the mid-1990s through early 2000s. Choose this part if you require a factory-style connector and bolt-on mounting, expect precise airflow measurement up to 9.25 m³/min, and want a backed replacement with a one-year warranty. Always verify year, engine size and connector type against the vehicle’s existing MAF or OEM reference numbers before purchase to ensure proper fitment.
