A-Premium Mass Air Flow Sensor for GM Trucks & Vans — 3-Pin MAF Assembly, Bolt-On Fit

The A-Premium 3-pin Mass Air Flow (MAF) Sensor Assembly accurately measures incoming air for select Chevrolet, GMC, Cadillac and Pontiac V8 engines and replaces OE units with a bolt-on, plug-and-play fit.

This replacement MAF sensor is engineered to restore correct air-measurement data to the engine control unit (ECU), helping optimize air/fuel calculations for older GM platforms. Designed for direct compatibility with many 1993–2002 Chevrolet and GMC trucks, vans and performance models, the unit uses durable PBT/glass and aluminum materials, a three-terminal blade connector and a four-bolt mounting pattern for straightforward installation.

Which vehicles will this A-Premium MAF sensor fit?

This assembly fits a wide range of GM vehicles from the mid-1990s to early 2000s. Confirm year, engine displacement and VIN engine code where noted before ordering to ensure exact fitment.

• Chevrolet: C1500, C2500, C3500, Camaro (1994–2002), Corvette (1994–2000), Express vans, Tahoe, K1500, P30
• GMC: C1500/C2500, K1500/K2500/K3500, P3500, Savana 2500/3500, Yukon
• Also compatible: Cadillac Escalade (1999–2000) and Pontiac Firebird (1993–2002), specific V8 and V6 engine matches listed in product details
• Cross-reference reference numbers like 19112572, 25008307, AF10056 when confirming OEM equivalence

How does the sensor attach and connect to the engine?

Installation uses the original mounting points and electrical interface for a fast swap in most cases. The assembly is bolt-on with a female 3-pin blade connector, designed to match factory harnesses without cutting or splicing.

• Mounting: four-bolt bolt-on flange for secure seating
• Electrical: female 3-pin blade connector, 12-volt maximum supply
• Materials: PBT with fiberglass reinforcement plus aluminum alloy housing for thermal stability
• Hardware: fits the OE footprint—use existing bolts or OEM replacements

What performance and measurement specs should I expect?

The sensor measures airflow across a range appropriate for the listed engines and returns readings within a tight tolerance to help the ECU manage injection timing. It’s rated for consistent accuracy over normal operating conditions, reducing intermittent signal problems common to aged units.

• Measuring range: 0–9.25 m³/min, suitable for V6 and V8 intake flows
• Accuracy: approximately ±3% under standard conditions
• Durability: engineered to reduce intermittent failures and extend service life
• Operational voltage: compatible with typical 12V automotive electrical systems

What else should I know before buying and how reliable is the part?

A-Premium backs this MAF with a one-year unlimited-mileage warranty and quality control checks. Match part reference numbers and vehicle compatibility in the listing to avoid returns, and inspect the intake and connector for contamination or damaged wiring during replacement.

• Warranty: one-year unlimited-mileage guarantee from A-Premium
• Reference numbers included for cross-checking OEM equivalents
• Pre-install tip: clean intake tract and throttle body to prevent sensor recontamination
• Failure signs: rough idle, hesitation or poor drivability suggest MAF diagnostics before replacement

Who is this for: This A-Premium three-pin MAF sensor is aimed at owners and mechanics maintaining mid-1990s to early-2000s GM trucks, vans and performance cars who need a direct-fit replacement that restores accurate airflow measurement without custom wiring. It’s helpful for do-it-yourself installers and professional shops that require OE-style fitment, robust materials and a backed warranty while servicing legacy GM platforms.
