GM GENUINE PARTS Mass Airflow (MAF) Sensor with Intake Air Temp — 213-4222 / 15865791, Direct-Fit OE Performance

GM Genuine Parts 213-4222 (15865791) is a direct-fit mass airflow sensor with an integrated intake air temperature sensor designed to restore accurate air measurement and support correct fuel delivery for compatible GM engines.

This replacement Mass Air Flow (MAF) sensor from GM Genuine Parts is engineered to the same specifications used in General Motors production vehicles. It accurately measures incoming air volume and intake air temperature so the engine control module (ECM) can calculate the proper fuel amount. Built and validated to match original equipment performance, this MAF sensor is offered as the recommended GM replacement for your vehicle’s factory-installed component.

How does this MAF sensor affect engine performance?

The MAF sensor provides the ECM with precise airflow and intake air temperature readings that influence fuel injection timing and quantity. When the sensor reports correct values, the engine runs closer to its intended air/fuel ratio, supporting consistent power delivery and smoother throttle response. A properly functioning MAF helps the vehicle adapt to changing driving conditions by supplying reliable input for the engine management system.

• Measures volume of air entering the intake tract
• Includes intake air temperature sensing to refine fuel calculations
• Supports consistent throttle response and drivability
• Designed for direct OE-style replacement and fitment

What makes the GM Genuine Parts 213-4222 a recommended replacement?

This component is manufactured to General Motors’ OE specifications for fit, form, and function. That means the connector type, mounting points, and electrical characteristics match the original part the vehicle came with. Using a GM-recommended part reduces the risk of compatibility issues and helps maintain the vehicle’s engineered performance characteristics.

• Built to GM OE standards for reliable fitment
• Electrical and mechanical compatibility with original harness and mounts
• Backed by General Motors validation and quality processes
• Suitable as a direct replacement for the original sensor

How do I know if this sensor is compatible with my vehicle?

Compatibility depends on your vehicle’s make, model, engine, and year; confirm using the GM part number (213-4222 / 15865791) against your VIN or parts catalog. When matched correctly, the sensor connects to the existing intake duct and wire harness without modification. If uncertain, consult a GM dealer or parts specialist with your VIN for exact fitment verification.

• Check vehicle parts catalog with part number 213-4222 or 15865791
• Verify compatibility using your VIN at a GM dealer or parts site
• Direct-fit design avoids custom adapters or wiring changes
• Installation should align with factory mounting and connector

What should I expect during installation and maintenance?

Installation is typically straightforward for a competent DIYer or technician: remove the old MAF sensor, plug in the replacement, and secure it to the intake assembly. Handle the sensor element carefully to avoid contamination; use only approved cleaners if service is required. After installation, the ECM may need a short drive cycle to relearn baseline airflow values.

• Replace by unplugging old sensor and mounting the new unit
• Avoid touching sensor element; contamination can affect readings
• Use specified cleaners and procedures when servicing
• Drive cycle may be necessary for ECM relearn and optimal operation

Who is this for: Technicians, DIY enthusiasts, and vehicle owners seeking a reliable, OE-quality MAF sensor replacement for compatible GM vehicles. It’s best for anyone who wants a part manufactured to GM specifications to maintain correct engine management performance without resorting to aftermarket adapters or altered calibration.
