OVERVIEW
The aFe Momentum GT is a dual sealed cold air intake system for the S58-powered BMW M3 and M4. It replaces both factory airboxes with smooth one-piece sealed housings moulded from heat-resistant XLPE (cross-linked polyethylene) polymer, each carrying a 6-1/2" tall 360-degree radial flow Pro 5R air filter on a 3-1/2" round flange. Large, clear sight windows let you inspect the filters without disassembling the system.
Each side uses a high-quality, computer-designed and dyno-tuned intake tube built from XLPE and high-performance silicone for heat-soak resistance and durability. aFe's patent-pending filter-to-housing interface uses half the number of parts of a traditional cold air intake, and the system is designed around the factory mounting locations for a hassle-free installation. Stainless-steel worm clamps and a premium bellows coupling are included, and the intake fits models equipped with the factory strut brace with no modification required.
