This Stage 2 cold air intake system produces 14 max horsepower, 18 lbs. x ft. torque and out-flowed the factory intake by 29% on the BMW 335i (F30) N55. This system includes a durable 18-gauge, powder-coated heat shield and features a washable/reusable conical Pro 5R air filter for maximum flow. This air filter is constructed with 100% polyurethane, for long life and multiple cleaning cycles. A huge 3.5 inch one-piece mandrel bent wrinkle-black powder-coated intake tube, maximizes air velocity providing maximum performance and throttle response. This is a direct bolt-on kit and requires no cutting or drilling.

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.

One-Piece Intake Tube: A large mandrel-bent intake tube is used to smoothly direct the increased air flow into the engine for maximum performance.

6" Tall Conical Filter: This intake utilizes a huge, 6" conical Pro 5R Filter. The Pro 5R performance air filter features 5-layers of progressively finer mesh cotton gauze media and is constructed with 100% polyurethane for long life and multiple cleaning cycles
