RADHLBNIU Mass Air Flow Sensor for Chevy GMC Buick — Direct-Fit (3.1L/3.4L/4.3L V6) OEM-Style Connector

RADHLBNIU Mass Air Flow (MAF) Sensor — a direct-fit replacement that restores accurate air intake measurement for select Chevy, GMC and Buick vehicles.

This MAF sensor is engineered to match original equipment fit and function for a wide range of GM models and engine variants, providing consistent airflow readings to the engine control system. It’s sold as a direct-replacement part to help correct drivability issues related to faulty airflow measurement, using factory-style connectors and mounting points for straightforward swap-in installation.

Which vehicles and engines will this sensor fit?

This sensor covers many GM passenger and light-truck applications across Chevy, GMC and Buick lines—mainly 3.1L, 3.4L and 4.3L V6 engines from the mid-1990s through the mid-2000s. Compatibility depends on the engine VIN code and the model year, so always cross-check your OEM part number or VIN-specific fitment list before ordering.

• Chevy: Astro, Blazer (S10/T10), Corsica, Impala, Lumina, Beretta — various V6 engines.
• GMC: Jimmy and Sonoma (S15/T15) across applicable model years and V6 displacements.
• Buick: Century, Regal, Rendezvous, Skylark with listed V6 configurations.
• Replaceable OEM numbers provided to verify exact match with your vehicle.

How do I confirm this is the correct replacement part for my car?

Match the replacement part numbers or compare the sensor’s connector, mounting holes and electrical pins with your existing unit. If you have the original part number or VIN-specific info, use those to confirm fitment; the product also lists many common OEM reference numbers to make verification easier.

• Compare your old sensor’s part number to the listed replace numbers (e.g., 25180303, 10332673).
• Verify connector shape and pin count against your vehicle’s sensor harness.
• Cross-check model year, engine size and VIN code where available.

What should I expect during installation and performance after replacement?

Installation is typically a simple bolt-and-plug swap using factory mounting points and the stock electrical connector—no special tools required beyond basic hand tools. After installation, the engine control unit will resume using accurate air-mass data for fuel trimming and ignition timing, which can resolve rough idle, hesitation or fuel-efficiency-related symptoms caused by a failing sensor.

• Standard hand tools suffice for removal and replacement.
• Plug-and-play electrical connector and OEM-style mounting.
• Clearing any engine codes after install may be required for ECU to relearn data.

Which OEM numbers does this sensor replace and why does that matter?

Knowing the OEM reference numbers helps ensure you get an exact-match replacement instead of a generic or incompatible unit. This RADHLBNIU sensor lists many commonly referenced part numbers to simplify cross-referencing with dealer parts or repair manuals.

• Common reference numbers included for verification (examples: 25008302, 2133458, 10332673).
• Using a matching reference reduces the chance of fitment or electrical mismatches.
• Helps when consulting mechanic, parts counter, or online VIN lookup tools.

Who is this for: This RADHLBNIU Mass Air Flow Sensor is intended for owners, mechanics and fleet technicians who need a reliable, direct-fit replacement for compatible Chevy, GMC or Buick V6 vehicles from the 1990s to mid-2000s. If your vehicle shows symptoms commonly associated with a failing MAF—such as irregular idle, hesitation, or check-engine codes related to airflow—this part provides an affordable OEM-style swap that simplifies repair and helps restore drivetrain responsiveness.
