This aFe POWER Momentum GT cold air intake system is engineered to maximize airflow and thermal protection for the BMW B58 engine. The smooth, one-piece sealed housing is constructed from heat-resistant cross-linked polyethylene (XLPE), housing a patent-pending filter-to-housing interface that reduces hardware complexity and simplifies installation. A large, clear sight window integrated into the housing allows for quick filter inspections without disassembly.

The system features a computer-designed, dyno-tuned intake tube and a 6-inch tall 360-degree radial flow air filter. The included Pro DRY S media uses three layers of oil-free synthetic material for maximum convenience and reliable filtration on the street. This intake outflows the factory system by 20%, measured at 245 CFM @ 7" H2O, providing a direct-bolt-on upgrade that utilizes factory mounting locations.
