Is your truck running rough, losing power, or throwing airflow-related codes you just can’t track down? The Walker Mass Air Flow (MAF) Sensor Assembly restores the critical airflow data your engine needs to run cleanly, efficiently, and strongly. By measuring both the volume and temperature of incoming air, this sensor helps your ECM calculate precise fueling for optimal combustion. When it starts to fail, you’ll notice poor throttle response, hesitation, rough idle, or reduced fuel economy. Replacing it with a Walker assembly restores smooth drivability, consistent power delivery, and reliable performance, whether you’re towing or daily driving.

Built for dependable OE-level performance, the Walker MAF Sensor Assembly is engineered with high-quality, durable components that withstand heat, vibration, and contamination from dust and oil vapors in the intake system. Each unit is individually tested for proper fit, form, and function before leaving production. Precision-calibrated sensing elements ensure accurate airflow readings across the full operating range, while the complete assembly design simplifies installation and restores factory-style performance without guesswork.
