aFe Magnum FORCE Stage-1 Cold Air Intake - BMW Z4 M (E85/E86) - 3.2L S54
The aFe Magnum FORCE Stage-1 Cold Air Intake replaces the factory air box on the E85/E86 BMW Z4 M with the 3.2L S54 six-cylinder. A 140mm (5-1/2in) Pro 5R filter sits in a one-piece heat shield that bolts to the factory mounting locations and keeps hot engine-bay air away from the filter.
The filter has an inverted top and mounts to a billet 3-angle adaptor that speeds air into the intake tract, while a black aluminium cover keeps temperatures down and gives quick access for servicing. The heat shield is 16-gauge steel in black powder coat. aFe rates the system at 90% more airflow than stock, and its dyno testing shows up to +8 kW (+11 hp) and +14 Nm.
Note: Suits the Z4 M roadster (E85) and coupe (E86) with the 3.2L S54. Installation by a professional is recommended.
