A-Premium Mass Air Flow Sensor Assembly for GM 3-Pin — OE Fit, ±3% Accuracy

A-Premium's 3-pin Mass Air Flow (MAF) Sensor Assembly measures intake airflow so the engine control unit can calculate correct fuel delivery for compatible Chevy, GMC, Cadillac and Pontiac V8/V6 engines.

This replacement MAF sensor is engineered to match OE fitment and electrical characteristics for many GM trucks, SUVs and performance cars from the mid-1990s to early 2000s. Built with a reinforced PBT and fiberglass housing and precision sensing elements, the unit bolts into the intake tract and provides the ECU with a steady, accurate airflow signal. It ships with the correct 3-pin connector footprint, four bolt mounting holes and is rated for 12V systems and measurement accuracy within ±3%.

Which vehicles will this A-Premium MAF sensor fit?

This assembly covers a long list of GM models across Chevrolet, GMC, Cadillac and Pontiac lines from roughly 1993–2002. Fitment includes many C/K trucks, Suburbans, Express/Savana vans, Camaro, Corvette and Firebird applications—check the detailed reference numbers and engine sizes before ordering.

• Chevrolet: C1500/C2500/C3500, Tahoe, Suburban, Express, Camaro, Corvette (various V8/V6 engines)
• GMC: C/K trucks, Yukon, Savana, P-series vans (multiple V6/V8 fits)
• Other: Cadillac Escalade and Pontiac Firebird where specified
• Compare reference numbers like 19112572, 25008307, AF10056 to confirm match

How accurate and durable is the sensor for everyday driving?

The sensor is specified to measure 0–9.25 m³/min of airflow with a stated accuracy of about ±3%, suitable for stock and mildly modified engines within the listed range. The housing uses PBT plus fiberglass and aluminum alloy components for strength and heat resistance, and the blade-style terminals and bolt-on mount secure a reliable electrical and mechanical connection.

• Measurement range: 0–9.25 m³/min
• Accuracy: approximately ±3%
• Materials: PBT+GF and aluminum alloy for durability
• Electrical: 3-pin female connector, 12V system compatibility

What installation details and connector specs should I know?

Installation is straightforward for anyone familiar with intake-tract components. The assembly replaces the OE unit using four bolt holes and the matching 3-pin blade connector; no special programming is required for most vehicles—simply secure the sensor, reconnect the wiring harness, and clear stored codes if needed.

• Mounting: bolt-on with four holes for OE-style fit
• Connector: female 3-pin blade terminal configuration
• Voltage: designed for standard 12V automotive systems
• Reference numbers included to verify fit before purchase
