Fits 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD (V8-6.6L LML diesel).

The aFe Power Momentum HD Pro DRY S Stage 2 intake system is engineered to provide significant performance gains and superior engine protection for your Duramax diesel. This system utilizes a unique, patent-pending filter-to-housing interface that allows for a larger filter size, increasing available air volume while simplifying the installation process. The CAD-designed, roto-molded intake tube and one-piece sealed housing work together to deliver a 52% increase in airflow over the factory intake, resulting in measured gains of up to +22 horsepower and +57 lbs. x ft. of torque.

At the heart of this system is the Pro DRY S 360-degree radial flow air filter. It features three layers of progressive synthetic media that achieve a 99.2% cumulative efficiency rating, providing maximum convenience with no oils required for servicing. The filter is reinforced with an external metal wrap to prevent collapse under high-load conditions. The high-quality housing also features a built-in auxiliary air inlet to pull in additional cool air for the intake system.
