Product Description

The aFe 54-11572 MagnumFORCE Stage-2 Cold Air Intake System is a performance-oriented intake upgrade engineered for 2004-2005 BMW 525i and 530i models equipped with the M54 inline-6 gasoline engine. This Stage-2 intake replaces the restrictive factory airbox and tubing with a precision-designed system that increases airflow, enhances throttle response, and delivers measurable gains in horsepower and torque. The large Pro 5R oiled cotton gauze air filter and molded plastic intake tube significantly improve airflow velocity compared to stock.

Featuring a durable powder-coated heat shield and a high-flow 6" conical filter with inverted top, this intake system draws cooler ambient air while reducing intake temperatures and maximizing volumetric efficiency. Installation is simple via direct bolt-on fitment to factory mounting points with no cutting or drilling required. The result is a noticeable improvement in engine sound, throttle responsiveness, and overall performance throughout the powerband.
