Fits select 2012-2018 BMW 335i, 435i, M2, and M235i (N55 engine).

Maximize your N55 engine's potential with the aFe Power Magnum FORCE Stage-2 Cold Air Intake System. This system is engineered to deliver a 44% increase in airflow over the factory intake, providing dyno-proven gains of up to 11 horsepower and 21 lbs. x ft. of torque. By replacing the restrictive factory air box with a high-flow, open-element design, this system provides a more aggressive intake sound and improved turbo spool-up.

The heart of this system is a 7-inch tall, 360-degree radial flow air filter featuring a 4-inch flange and Pro 5R media. This five-layer, progressively finer oiled cotton gauze media ensures maximum filtration and airflow for street and track use. The filter is housed in a durable XLPE (cross-linked polyethylene) polymer shield that utilizes a patent-pending filter-to-housing interface to reduce part count and simplify installation.

Construction features include a computer-designed, dyno-tuned XLPE intake tube that resists heat soak and maintains a perfect fit. This is a direct bolt-on system that utilizes factory mounting locations, requiring no cutting or permanent vehicle modifications.
