A-Premium Mass Air Flow Sensor for Hyundai & Kia 5-Pin (4-Cyl) — Direct Replacement, ±3% Accuracy

This direct-replacement MAF sensor from A-Premium is designed to restore correct air-fuel metering on select Hyundai and Kia 4-cylinder vehicles. Built from PBT+GF30 and aluminum alloy, the unit mounts with two bolts, uses a five-pin pin-style terminal, and operates within a 0–9.25 m³/min measurement range with ±3% accuracy. The sensor helps the engine control unit (ECU) calculate injector pulse widths so your engine runs closer to factory calibration.

Which vehicles and engines will this A-Premium MAF sensor fit?

This assembly is intended for 4-cylinder models only; it is not compatible with 6-cylinder engines. Verify the vehicle VIN and engine displacement against the listed fitments before purchase.

• Hyundai: Accent 2006 1.6L, Elantra 2003–2010 2.0L, Sonata 2006–2008 2.4L, Tiburon 2003–2008 2.0L, Tucson 2005–2009 2.0L.

What are the key specifications and build details of this MAF sensor?

The A-Premium assembly is engineered to match OE-style mounting and electrical connections for the listed 4-cylinder applications. It offers robust materials and a performance envelope suitable for everyday driving conditions.

• Terminal quantity/type: 5 pins (pin-style connector).
• Mounting: 2-bolt bolt-on installation; housing included.
• Materials: PBT+GF30 plastic with aluminum alloy components; color: black.
• Electrical: maximum supply voltage 12 V; measuring range 0–9.25 m³/min; accuracy ±3%.

How does replacing the MAF sensor affect engine performance?

A correctly reading MAF sensor helps the ECU determine the proper fuel delivery and ignition adjustments. Replacing a failing sensor can reduce rough idling, improve throttle response, and stabilize fuel trim readings when the sensor is the root cause of drivability issues.

• Restores accurate intake airflow data to the ECU for correct injector timing.
• Reduces intermittent sensor failures that cause check-engine lights or hesitation.
• Maintains factory tolerances to prolong downstream component life.

Are there reference numbers and installation notes I should check?

Compare part numbers and confirm engine type before installing to ensure fitment. The listing includes multiple reference numbers to help verify cross-compatibility with OE and aftermarket catalogues.

• Reference numbers: 28164-23700, 28164-23720, 28164-25000, 2816423700, 2816423720, 2816425000.
• Additional codes: 5WK96431, 5WK96491, MAS0255, 74-10114, 7410114, 917-892, AFEL03, 5S2982.
• Important: For 4-cylinder models only — verify your engine and VIN before purchase.

Who is this for? If you own one of the listed Hyundai, Kia, or Dodge Attitude 4-cylinder models and you’re seeing symptoms such as unstable idle, poor throttle response, or diagnostic trouble codes pointing to airflow measurement, this A-Premium 5-pin MAF sensor is intended as a cost-effective, OE-style replacement. Technically inclined owners can bolt it in as a direct swap; anyone unsure should scan trouble codes or consult a qualified mechanic. A-Premium backs this part with a one-year unlimited-mileage guarantee and recommends confirming the MAF is the failing component before replacement.
