A-Premium Mass Air Flow Sensor 5-Pin for Hyundai & Kia — OE-Fit, ±3% Accuracy

The A-Premium 5-pin Mass Air Flow (MAF) Sensor Assembly measures incoming air to help your Hyundai or Kia engine get the right fuel-to-air ratio for reliable running.

If your vehicle is showing rough idle, reduced fuel economy, or diagnostic trouble codes related to air metering, a worn or failing MAF sensor can be the cause. This A-Premium replacement is built to match OE fit and function for many 4-cylinder Hyundai and Kia models, offering a bolt-on installation, durable PBT+GF30 and aluminum alloy construction, and measurement accuracy within ±3% across its specified range.

Which vehicles will this MAF sensor fit?

This assembly is intended for 4-cylinder applications across selected Hyundai and Kia model years. Confirm your engine size and part reference before ordering to avoid fitment issues; it is not compatible with 6-cylinder engines.

How accurate and durable is the sensor?

The A-Premium unit is engineered for stable readings and long life under normal driving conditions. Its sensing range and stated accuracy support reliable engine management without frequent replacement.

• Measuring range: 0–9.25 m³/min with ±3% accuracy
• Maximum supply voltage rated for 12V systems
• Housing and internals made from PBT+GF30 and aluminum alloy for heat and vibration resistance
• Bolt-on mounting with two bolt holes and five-pin electrical terminal

What symptoms might mean the MAF sensor needs replacing?

A failing MAF sensor can cause drivability and emissions-related symptoms; however, verify codes and rule out related components before replacing. Scanning for trouble codes and checking connectors and wiring can prevent unnecessary parts changes.

• Common signs: unstable idle, hesitation on acceleration, reduced fuel economy, or engine warning light
• Recommended: scan ECU codes and inspect intake tubing for leaks or contamination
• Note: replace only if diagnosis confirms MAF failure to save time and cost

How do I install this sensor and what should I check after installation?

Installation is straightforward for most DIYers or technicians: remove the intake duct, unplug the electrical connector, unbolt the old sensor, and fit the new assembly in the same orientation. After installation, clear any stored codes and perform a short drive cycle to confirm proper operation.

• Mounting: bolt-on with two bolts and five-pin connector; match orientation to original sensor
• Post-install: clear ECU codes and verify stable idle and throttle response
• Tip: inspect intake hose clamps and vacuum lines to ensure airtight sealing

Who is this for? Drivers and mechanics seeking a cost-effective, OE-style replacement MAF sensor for compatible 4-cylinder Hyundai and Kia vehicles will find this A-Premium assembly suitable. It’s aimed at owners who want dependable air-flow measurement with easy bolt-on installation, backed by a one-year unlimited-mileage guarantee—assuming correct diagnosis and fitment. If you’re unsure about compatibility, confirm engine size and reference numbers or consult a qualified mechanic before purchasing.
