aFe POWER Magnum FORCE Stage-2 Pro 5R Cold Air Intake System 15-19 BMW M3/M4 3.0L

These 6" tall 360-degree radial flow air filters feature our pre-oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum performance. This media provides your engine with the largest amount of high-flowing air and delivers the highest power gains in most cases, making it perfect for street and/or track use. Their inverted top makes for more filter surface area, resulting in longer service intervals. The included high-performance air filters are surrounded by open-element XLPE (cross-linked polyethylene) polymer housings that minimize warm engine air for maximum performance. Their open design allows for easy viewing of the air filters and delivers an aggressive Air Intake sound. They utilize the vehicle's factory air inlet with no additional hardware. This system features high quality, computer-designed, dyno-tuned intake tubes to achieve maximum power gains while maintaining a perfect fit. Their black XLPE material is heat soak resistant and extremely durable. The longer tube passing in front of the engine features aluminum trim, securing the coolant hose and giving a unique look to your engine bay. An optional carbon fiber trim piece can be purchased separately (PN 54-13032CC). This is a direct fit intake system that utilizes factory mounting points and requires no cutting or modifications. All necessary clamps, couplings, and hardware are included. Its revolutionary design, featuring our patent pending filter-to-housing interface, uses half the number of parts of a traditional cold air intake system.
