Walker Mass Air Flow Sensor 08-10 Ford 6.4L Powerstroke

Is your truck feeling sluggish, hesitating under throttle, or losing fuel economy without a clear cause? The Walker Mass Air Flow (MAF) Sensor restores the precise airflow measurement your engine depends on to deliver the right amount of fuel at the right time. This sensor continuously measures incoming air volume and sends that data to the ECM to maintain optimal combustion. When it starts to fail, you’ll see symptoms such as a rough idle, poor acceleration, black smoke, or inconsistent power delivery. Replacing it with a Walker sensor brings back crisp throttle response, improved drivability, and reliable performance whether you’re towing or daily driving. Built for long-term reliability in harsh engine bay conditions, the Walker MAF sensor uses high-quality OE-matched components designed to withstand heat, vibration, and contamination from dust and oil vapors. Its precision sensing element is engineered to maintain accurate airflow readings across a wide operating range, ensuring stable communication with the ECM over time. Each unit is 100% tested for fit, form, and function to meet OE standards, providing consistent signal accuracy, dependable operation, and long service life in demanding diesel applications.
