Is your truck running rough, lacking power, or struggling with poor fuel economy? The Walker Mass Air Flow (MAF) Sensor is designed to restore precise airflow readings so your engine can perform the way it should. By accurately measuring the amount of air entering your intake, this sensor allows your ECM to adjust fuel delivery and maintain the ideal air-to-fuel ratio properly. A failing MAF sensor can cause hesitation, sluggish acceleration, and inefficient performance, but replacing it with this direct-fit unit brings back smooth throttle response, consistent power, and improved overall drivability. Perfect for keeping your Duramax running strong, whether you're towing or daily driving.
Built for reliability in demanding engine conditions, the Walker MAF Sensor is manufactured with high-quality components that withstand heat, vibration, and contamination from the intake system. Its durable construction protects the sensitive sensing elements while maintaining fast and accurate response times. Engineered to meet OE specifications and 100% tested for performance, this sensor ensures proper fit, long service life, and dependable operation in harsh diesel environments.
