The aFe MagnumFORCE Stage-1 cold air intake for the BMW Z4 (E85) 2003–2005 L6-3.0L M54 replaces the factory intake with a rotomolded tube and enclosed 16‑gauge heat shield. It uses a washable, reusable Pro 5R 360° conical air filter made from polyurethane and a 3-angle adapter to increase air velocity. The system is credited with a claimed gain of about 6 hp and 7 lb-ft of torque and a significant CFM flow increase per the supplied market material; it ships with a two-year limited warranty.
