Product Description

The aFe Power Magnum FORCE Stage-1 Pro 5R Cold Air Intake System 54-10601 is a direct-fit performance upgrade engineered for classic BMW 5-Series E39 models with the 2.8L M52 or 2.5L M54 inline-six engines. Designed to replace the restrictive stock intake, this Stage-1 system uses a high-flow Pro 5R oiled radial filter to increase airflow and improve throttle response. The large 5½" conical filter media and unique 3-angle billet adapter help deliver more air with less restriction - translating into measurable gains in horsepower and torque.

Built around a robust one-piece heat shield that uses factory mounting points, the intake installs quickly without cutting or fabrication and comes complete with all necessary hardware. The washable and reusable Pro 5R filter makes maintenance simple, and the oiled media ensures excellent filtration performance. This intake is a popular choice for BMW enthusiasts looking to enhance engine breathing and performance while retaining a clean, factory-like fit and finish.
