aFe Momentum Pro 5R Cold Air Intake System 15-18 BMW M3/M4 (F80/82/83) L6-3.0L (tt) S55

The smooth one-piece sealed housings with auxiliary air inlets are used to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. Large, clear sight windows are used for a hassle-free filter inspection and an aggressive style. This System uses CAD designed, dyno-tuned, roto-molded intake tubes to achieve maximum power gains while maintaining a perfect fit. This intake system utilizes oil-free, large 5" tall conical 360 degree radial flow performance air filters with 3-Layer progressively finer porosity synthetic media for maximum convenience. Premium clamps are used for strength and durability while also providing the most secure installation available. Momentum intakes are designed with fewer parts for a quick and simple installation.
