aFe Track Series Stg 2 Carbon Fiber Intake w/Pro 5R Media 15-20 BMW M3/M4(F80/82/83) L6-3.0L(tt) S55

Large Five Layer Performance Air Filters: 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. Dyno-Tuned Intake Tubes: This system features high quality, computer-designed, dyno-tuned intake tubes to achieve maximum power gains while maintaining a perfect fit. Their durable 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. Optional carbon fiber trim pieces can be purchased seperately (PN 54-13032CC). One-Piece Housing: The included 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. The system utilizes the vehicle's OE air inlet with no additional hardware. They
