Product Description

The aFe 53-10008D Quantum Pro DRY S Cold Air Intake System is engineered specifically for 2001-2004 Chevrolet Silverado HD and GMC Sierra HD trucks equipped with the 6.6 L Duramax LB7 diesel V8 engine. Designed to replace the restrictive factory airbox and intake tract, this Magnum Force Stage 2 system features a large, high-flow Pro DRY S dry synthetic filter that requires no oiling and is washable for easy maintenance. The performance-oriented intake tube and heat-shield design help deliver cooler, denser air to the engine, improving volumetric efficiency and overall airflow.

Installation is straightforward with direct bolt-on fitment using the factory mounting points and included hardware - no cutting or drilling is required. With measured increases in airflow, this intake system supports improved throttle response, stronger torque and horsepower gains compared with the stock system. Please note this intake is **not CARB exempt** and therefore **cannot be used in California or other CARB-required states**. Fitment is confirmed through 2004 for the supported Duramax diesel models.
