Is your truck feeling sluggish, smoking, or struggling with poor throttle response and fuel economy? The Walker Mass Air Flow (MAF) Sensor Assembly restores the precise airflow measurement your engine depends on to run clean and strong. This sensor assembly reads the volume and density of incoming air and sends that data to the ECM so it can properly calculate fueling and boost control. When it fails, you can see rough idle, reduced power, hard starts, or inconsistent performance under load. Replacing it with this direct-fit assembly restores crisp throttle response, smooth drivability, and reliable performance whether you’re towing heavy loads or daily driving.

Built for long-term durability in demanding diesel applications, the Walker MAF Sensor is manufactured with high-quality, OE-matched components that withstand heat cycling, vibration, and contamination from dust and oil. The sensing element is engineered for precise airflow measurement across a wide operating range, ensuring stable and accurate signal output to the ECM. Each unit is fully tested for fit, form, and function to meet OE specifications, delivering consistent reliability, easy installation, and long-lasting performance in harsh operating environments.
