How does this MAF sensor match OEM performance and references?

A-Premium designed this sensor to meet OEM electrical and mounting standards, including terminal type and bolt configuration, so it installs cleanly into the factory air duct. It carries reference numbers often cross-referenced to aftermarket listings, but is not compatible with OE part MAF438. Measure and compare reference numbers to your original part to confirm fit.

• Reference numbers: MAS0467, MA447, MAF0123, 2451403, 226803VA0A
• Not compatible with OE MAF438 — verify your original part number
• 4-pin terminal configuration and two-bolt mounting for direct replacement

What are the key specs and material details I should know?

The sensor is constructed from high-strength PBT+GF30 plastic with aluminum alloy components for durability and heat resistance. It operates up to a maximum supply voltage of 5.5V, measures airflow from 0 to 480 kg/h, and claims measurement accuracy around ±2%, suitable for engine control feedback and diagnostics.

• Material: PBT+GF30 reinforced plastic and aluminum alloy
• Electrical: 4 pins, maximum supply voltage 5.5V
• Performance: measuring range 0–480 kg/h, accuracy ±2%
• Mounting: bolt-on with two bolt holes; housing not included

How should I approach installation and diagnosis?

Scan your vehicle’s trouble codes and confirm MAF sensor fault codes before replacement to avoid unnecessary parts changes. If you proceed, ensure the connector pin count and mounting holes match the factory sensor; a qualified technician can complete calibration or clearing of intermittent faults after install.

• Scan OBD-II codes to confirm MAF-related errors
• Verify 4-pin connector and two-bolt mounting match vehicle
• Consider professional installation for accurate sensor clearing and diagnostics

Who is this for? This A-Premium 4-pin MAF sensor suits vehicle owners and mechanics seeking an economical, OEM-like replacement for Nissan and Infiniti vehicles listed above. It's intended for anyone replacing a failed or unreliable mass air flow sensor who needs a direct-fit, robust component with clear reference numbers and a one-year unlimited-mileage warranty. If you’re uncertain about fitment, confirm your original part number and production date range or consult a mechanic before purchasing.
