Product Description

The aFe 54-10451 Magnum FORCE Stage-1 Cold Air Intake System with Pro 5R filter is a performance-focused intake upgrade engineered for 2001-2006 BMW 3-Series (E46) and 2004-2006 BMW X3 (E83) models equipped with the M54 inline-6 engines. Replacing the restrictive factory airbox and filter with a high-flow Pro 5R oiled cotton gauze filter and a precision-designed intake assembly, this Stage-1 system increases engine airflow, enhances throttle response, and delivers measurable gains in horsepower and torque over stock. The one-piece heat shield and aluminum cover help isolate the intake from engine heat, promoting cooler, denser air delivery for improved combustion efficiency.

Installation is straightforward with a direct bolt-on design that uses existing OEM mounting points and includes all required components - no drilling or modifications are required. The washable and reusable Pro 5R filter media offers long service life with periodic maintenance. This intake is engineered specifically for the listed BMW applications, delivering stronger acceleration, enhanced engine sound, and improved performance while maintaining daily-driving practicality.
