2017-2022 BMW 540i/740i/840i Momentum GT Cold Air Intake System by aFe Power

This 6” tall 360-degree radial flow air filter features a 4-1/2” round flange and our oiled Pro 5R media with five layers of progressively finer cotton gauze media for maximum airflow and performance. This media is best for street and track use.

The smooth one-piece sealed housing, constructed of heat-resistant XLPE (cross-linked polyethylene) polymer, features our patent-pending filter-to-housing interface. A large, clear sight window allows for hassle-free filter inspection, without having to disassemble your system.

This system features a high-quality, computer-designed, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. Its XLPE material is heat-soak resistant and extremely durable.

This intake is designed to use factory mounting locations, minimizing the use of unnecessary hardware, and ensuring a perfect fit every time. Its revolutionary design, featuring our patent-pending filter-to-housing interface uses half the number of parts of a traditional cold air intake system.

Stainless steel worm clamps are included for strength, and a premium bellows coupling allows for ample flexibility. Momentum GT intakes are designed with fewer parts for a fast and easy installation.
