Product Description

The aFe 54-11081 MagnumFORCE Stage-1 Cold Air Intake System is a performance upgrade designed specifically for 2004-2005 BMW 545i and 645Ci models equipped with the N62 4.4L V8 gasoline engine. This Stage-1 intake replaces the restrictive factory airbox with a high-flow intake that increases airflow and improves throttle response. The washable and reusable Pro 5R air filter provides excellent filtration while maximizing air delivery to the engine for noticeable horsepower and torque gains.

Featuring a durable powder-coated heat shield and a precision-engineered 3-angle adaptor to smooth airflow, this intake system is designed for direct fitment using factory mounting points with no modifications required. The improved airflow also enhances engine sound and responsiveness, making it an ideal first upgrade for performance-minded BMW owners.
