A-Premium Mass Air Flow (MAF) Sensor Assembly 5‑Pin for Chevy GMC – Direct Fit, ±3% Accuracy

The A-Premium 5-pin mass air flow (MAF) sensor assembly accurately measures intake air volume and density for compatible Chevy, GMC, Buick, Pontiac, Cadillac and Saturn engines.

This replacement MAF sensor is a direct-fit, bolt-on unit built from PBT+GF30 plastic and aluminum alloy. Designed to match OEM electrical and mounting interfaces, it offers a 5-pin terminal configuration, two mounting holes and a measuring range up to 9.25 m³/min with ±3% accuracy. The sensor communicates air mass information to the engine control module so fuel delivery and ignition timing can be adjusted for different operating conditions.

Which vehicles will accept this A-Premium 5-pin MAF sensor?

This assembly fits a wide group of GM vehicles across Chevrolet, GMC, Buick, Pontiac, Cadillac and Saturn lineups from mid-2000s to early 2010s. Install compatibility depends on engine variant and model year—always verify with part references or your vehicle VIN before buying.

• Buick: Allure, Enclave, LaCrosse, Lucerne, Rendezvous, Terraza (selected years and engines)
• GMC: Acadia (2007–2008 3.6L)
• Pontiac: G6, G8, Grand Prix, Montana, Torrent (selected years/engines)
• Chevrolet: Captiva Sport, Equinox, Impala, Malibu, Monte Carlo, Uplander (selected years/engines)
• Cadillac & Saturn: DTS, Aura, Outlook, Relay, Vue (selected years/engines)

How does the sensor’s design ensure reliable readings?

Material choice and precise manufacturing tolerances help the unit hold calibration and resist thermal or vibrational stress. The aluminum alloy and glass-filled PBT housing protect the sensing element while the 5-pin electrical interface matches OEM signal and supply lines for consistent communication with the ECU.

• Housing: PBT+GF30 plastic for heat and chemical resistance
• Structural parts: aluminum alloy for durability and heat dissipation
• Electrical: 5-pin terminal configuration matches original harness connectors
• Mounting: two bolt holes for a secure, bolt-on installation

What are the technical specifications I should know?

This MAF sensor operates on a standard 12-volt supply and measures airflow between 0 and 9.25 cubic meters per minute with an advertised accuracy near ±3%. It’s intended as a direct replacement to restore proper airflow readings and support the engine management system’s fuel calculations.

• Terminal quantity: 5 (pin type)
• Mounting: 2 bolt holes, bolt-on installation
• Measuring range: 0–9.25 m³/min; accuracy ±3%
• Max supply voltage: 12 volts; housing included

Will this A-Premium sensor replace my OEM part numbers?

The assembly cross-references several OEM and aftermarket numbers used across GM vehicles. If your original part number matches any listed references, this unit is likely a compatible replacement; always compare connector shape and mounting points before ordering.

• Common reference numbers: 74-10113, 15911983, 10349461 and 2451133
• Other cross-refs: SK2451133, 5S6708, MG0022, MF21136
• Also referenced as SU8208, AA17410113 and SU10588 in some catalogs

Who this is for: mechanics, DIY enthusiasts and fleet owners replacing a failing or out-of-spec mass air flow sensor on eligible GM vehicles. Pick this unit if you need a direct-fit 5-pin assembly with OEM-style mounting and reliable airflow measurement for fuel-trim and engine management systems. If you are unsure about fitment, check your vehicle’s part number or consult a technician before purchase.
