Product Description

The aFe 54-10671 Magnum FORCE Stage-1 Cold Air Intake System with Pro 5R filter is engineered specifically for 2001-2003 BMW 530i models equipped with the 3.0 L M54 inline-6 engine. This Stage-1 system replaces the restrictive factory airbox with a high-flow Magnum FORCE intake that dramatically increases airflow into the engine for improved throttle response and enhanced performance. The included 5-1/2" radial-flow Pro 5R conical filter features oiled cotton gauze media that is washable and reusable, delivering excellent filtration and strong airflow gains for better engine breathing.

Featuring a billet 3-angle adapter and one-piece powder-coated heat shield, this intake improves airflow direction and helps isolate the filter from engine heat, promoting cooler intake air for improved combustion efficiency. Installation is straightforward with a direct bolt-on design that uses existing factory mounting points - no cutting or drilling are required. With measured gains in horsepower and torque and 50-state CARB legal status on covered applications, this Magnum FORCE Stage-1 intake is an excellent performance upgrade for street and highway use on supported BMW 530i applications.
