aFe Magnum FORCE Stage-2 Cold Air Intake - BMW Z4 3.0si (E85) - 3.0L N52
The aFe Magnum FORCE Stage-2 Cold Air Intake replaces the factory air box and intake tract on the facelifted E85 BMW Z4 3.0si roadster with the 3.0L N52 six-cylinder. A conical Pro 5R filter sits in a one-piece 18-gauge heat shield finished in black powder coat, with a 3-angle adaptor to smooth the airflow.
A heat-insulating moulded plastic tube replaces the factory intake tract and improves volumetric efficiency, and a black powder-coated top gives the kit a clean, stealthy look. aFe's dyno testing shows up to +13 kW (+18 hp) and +20 Nm over the factory intake.
Note: Suits the 2006-2008 E85 Z4 roadster with the 3.0L N52; aFe does not list the E86 coupe. Installation by a professional is recommended.
