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

The aFe Momentum HD Stage-2 Si sealed air intake system is engineered for maximum performance and protection on LML Duramax diesel engines. Featuring a one-piece, roto-molded housing, this system incorporates a massive 1,000cfm Pro 10R air filter with a unique, patent-pending filter-to-housing interface that simplifies installation. The CAD-designed intake tube is precision-tuned to optimize airflow, resulting in significant power gains of up to +22 horsepower and +57 lbs. x ft. of torque while outflowing the factory intake by 52%.

Designed for ease of maintenance, the housing includes a built-in clear sight window for instant filter inspections without requiring disassembly.
