Product Description

The aFe 54-31912 Magnum FORCE Stage-2 Cold Air Intake System with Pro 5R oiled air filter is a high-flow performance upgrade designed for BMW vehicles equipped with the N55 3.0L turbocharged inline-6 engine. This intake replaces the restrictive factory airbox with a large, five-layer Pro 5R oiled filter and a CAD-designed roto-molded intake tube, allowing for significantly increased airflow into the engine. The enhanced airflow and optimized intake path improve throttle response and help unlock additional horsepower and torque potential compared to the stock intake.

Installation is straightforward with a direct bolt-on design that uses factory mounting points, requiring no cutting or drilling. The washable and reusable Pro 5R filter media simplifies maintenance while maintaining strong filtration performance. Fitment is confirmed for BMW 135i, 335i, 335i xDrive models from 2011-2013 and BMW X1 xDrive35i from 2013-2015. This intake is intended for performance use; it may not be emissions-legal in all regions - verify local regulations before installation.
