Magnum FORCE Stage 2 Cold Air Intake System

The aFe Power Magnum FORCE Stage 2 cold air intake system is engineered to replace the factory air box and intake tract for select BMW 328i and 328i xDrive (F30 chassis) models from 2012-2016 with the N20 Turbo engine. This system is designed to increase airflow by 38% over the stock intake, resulting in a claimed increase of up to 11 max horsepower and 15 lbs. x ft. of torque. The intake features a large, 7-inch tall conical Pro 5R air filter, constructed with five layers of progressively finer mesh cotton gauze oiled media for maximum airflow and excellent filtration. The progressively layered media allows the filter to maintain high flow rates even when dirty, and it has been tested at 98.6% efficiency. The 3-inch, one-piece mandrel-bent intake tube is wrinkle-black powder-coated to maximize air velocity and improve throttle response. The filter utilizes a unique patent-pending flange retention design that requires no hardware for a quick, hassle-free installation. The one-piece, black powder-coated 18-gauge heat shield snaps onto the lower half of the factory air box, utilizing factory mounting locations to keep warm engine air out and ensure maximum performance. Note: This intake system is not CARB exempt and is not legal for sale or use in California or vehicles registered with the California Department of Motor Vehicles.
