Enhance your BMW M3 or M4 with the aFe Power Magnum FORCE Stage-2 Cold Air Intake System, designed specifically for models from 2015 to 2019. This system features a 6-inch tall, 360-degree radial flow air filter equipped with our oil-free Pro DRY S media, which incorporates three layers of synthetic material to maximize filtration efficiency and dust capacity without the need for oil. The progressive layering ensures optimal airflow and protection, making it ideal for street driving conditions. The inverted top design increases filter surface area, promoting longer service intervals and consistent performance. Encased in a durable, heat soak resistant XLPE polymer housing, the open-element design provides visual access to the filters and delivers an aggressive intake sound for enthusiasts seeking an enhanced auditory experience. The system is engineered to connect seamlessly to the vehicle's factory air inlet, requiring no additional hardware or modifications, simplifying installation. It utilizes high-quality, computer-designed, dyno-tuned intake tubes that optimize airflow for maximum power gains, with measured flow rates reaching 765 CFM at 7 inches of water. The aluminum-trimmed longer intake tube not only secures the coolant hose but also adds a distinctive look to the engine bay. An optional carbon fiber trim piece (sold separately) allows further customization. The patent-pending filter-to-housing interface reduces the parts count compared to traditional cold air intake systems, streamlining installation and maintenance. This intake system delivers significant performance improvements, with dyno tests showing gains of up to 19 horsepower and 17 pound-feet of torque, and it outperforms the factory intake by 32%. The inclusion of all necessary clamps, couplings, and hardware ensures a straightforward installation process. Built for durability and performance, the aFe Magnum FORCE intake combines innovative design with proven results, making it an excellent upgrade for street-driven BMW M models seeking enhanced airflow, sound, and power.
