This Stage-2 cold air intake system resulted in 11 max horsepower, 15 lbs. x ft. torque and out-flowed the factory intake by 38% on the 2012-2014 BMW 328i (F30) N20 Turbo. This system includes a durable 18-gauge, powder-coated heat shield and features a washable/reusable conical Pro 5R air filter for maximum flow. The Pro 5R air filter uses five layers of progressively finer mesh cotton gauze oiled media to provide maximum airflow for best performance results. A 3 inch one-piece mandrel bent wrinkle-black powder-coated intake tube and bracket, maximizes air velocity providing maximum performance and throttle response. This is a direct bolt-on kit that requires no cutting or drilling on OEM parts.

Filter Flange Retention Design: The air filter uses a unique (patent pending) flange retention design that requires no hardware to mount the filter to the heat shield to provide a quick hassle-free installation with minimal hardware.

Dyno Tested Intake Tube: This dyno tested intake tube is designed to maximize air velocity and uses the latest engineering tools for maximum performance. This large intake tube is mandrel-bent to smoothly direct the increased airflow into the engine.

7" Tall Conical Filter: This intake utilizes a huge, 7" conical Pro 5R Filter. This filter features 5-layers of progressively finer mesh cotton gauze oiled media to provide maximum flow with excellent filtration. The progressive layering of media allows the filter to flow at high levels, even when dirty. The Pro 5R filter media has been tested at 98.6% efficient.

One-Piece Heat-Shield: The air filter is housed in a one-piece, black powder-coated 18-gauge heat shield that keeps warm engine air out for maximum performance. This one-piece heat shield snaps onto the lower half of the factory air box to provide a quick and easy installation utilizing factory mounting locations.

Note: This intake system is not CARB exempt at this time and is not legal for sale in California or use on vehicles registered with the California Department of Motor Vehicles.
