Enhance your BMW X3 or X4 M40i with the aFe Momentum GT Pro 5R Cold Air Intake System, designed for optimal performance and maximum airflow. This system features a 6-1/2 inch tall, 360-degree radial flow air filter with a 5-1/2 inch round flange, using our oiled Pro 5R media. The five layers of progressively finer cotton gauze media are engineered for superior filtration efficiency and increased airflow, making it ideal for both street and track use. The smooth, one-piece sealed housing is constructed from heat-resistant XLPE (cross-linked polyethylene) polymer, providing durability and resistance to heat soak. The patent-pending filter-to-housing interface simplifies installation, reducing parts count and ensuring a secure, leak-proof fit. A large, clear sight window allows for quick inspection without disassembly, saving time and effort during maintenance. The intake tube is computer-designed and dyno-tuned to maximize power gains while maintaining a perfect fit using factory mounting points, minimizing hardware requirements. Its innovative design, featuring fewer components than traditional cold air intakes, offers a cleaner, more efficient setup. Included stainless-steel worm clamps provide strength and reliability, while a premium silicone coupling delivers flexibility and ease of installation. This system is engineered to deliver noticeable performance improvements, with enhanced airflow, horsepower, and throttle response, making it a high-quality upgrade for your BMW's engine intake. Designed specifically for 2020 to 2024 BMW X3 and X4 M40i models, the aFe Momentum GT Pro 5R Cold Air Intake ensures a seamless fit and reliable operation, backed by a reputation for quality and precision engineering.
