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 DRY S air filter for maximum flow. The Pro DRY S air filter uses three layers of progressively finer mesh synthetic "oil-free" media to provide maximum airflow for the 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 DRY S Filter. This filter features 3-layers of progressively finer mesh synthetic "oil-free" 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 DRY S non-oiled synthetic air filter requires no oils for cleaning for maximum convenience.

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.

Good product

Overall a good product. Difficult to notice the power increase but that was expected. Easy to install, looks good in the engine bay. Now makes the noise of induction much louder, and you’re able to hear the wastegate when you come off the throttle. Also makes the engine overall louder. Only downside is the car now hunts on cold start, but that goes after a few minutes.
