Boost the performance and efficiency of your naturally aspirated BMW with the aFe Power Magnum FORCE Stage 2 Si intake system. This sealed intake is engineered to replace the restrictive factory airbox, delivering up to 12 horsepower and 15 lbs-ft of torque gains while outflowing the stock unit by 56%. The system features a custom-designed, rotomolded plastic intake tube with a built-in velocity stack adapter to maximize intake velocity and volumetric efficiency.

At the heart of this system is a 6-inch conical Pro 5R air filter. Featuring five layers of progressively finer mesh cotton gauze media, this washable and reusable filter provides maximum airflow for increased throttle response. The filter is housed in a durable sealed unit with two auxiliary air inlet ducts, ensuring a steady supply of cool air. A vacuum-formed ABS plastic cover with a sleek carbon fiber finish protects the filter from engine heat while adding an aggressive look to your engine bay.
