Built to meet or exceed OEM specifications, this sensor features high‑quality internal components and a rugged housing designed to handle heat, vibration, and contaminants in the intake tract. It installs as a direct replacement in the air intake path and provides a consistent, accurate signal output for precise engine control. Engineered and tested for long service life, it helps eliminate airflow‑related trouble codes and keeps your Duramax diesel running at its best mile after mile
