Fits select 2006-2007 Chevrolet Silverado and GMC Sierra 2500 HD/3500 and Classic models (V8-6.6L).

The aFe POWER Momentum HD Stage-2 SI intake system is engineered to provide maximum airflow and protection for Duramax-equipped GM trucks. This sealed system features a unique, one-piece housing designed to eliminate multiple components and ensure a cool, dense air charge. The integrated sight glass allows for quick filter inspections without dismantling the assembly, while the auxiliary air scoop provides additional air volume when needed (includes a urethane plug for cold-weather use).

At the core of this system is the massive 360-degree radial flow air filter. Utilizing the oil-free PRO DRY S media, it features three layers of progressive synthetic material for high filtration efficiency and easy maintenance. The patent-pending filter-to-housing interface and 6-inch flange provide a secure, leak-free seal. Installation is straightforward, utilizing 2-ply reinforced silicone hump couplers and premium stainless steel T-bolt clamps for a durable connection that stands up to high-vibration diesel environments.
