aFe Magnum FORCE Stage-1 Cold Air Intake - BMW Z4 2.5i (E85) - 2.5L M54
The aFe Magnum FORCE Stage-1 Cold Air Intake replaces the factory air box on the E85 BMW Z4 2.5i with the 2.5L M54 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 18-gauge steel heat shield is powder coated, and a 3-angle filter adaptor smooths the air on its way into the intake tract. aFe rates the system at 71% more airflow than stock, and its dyno testing shows up to +3 kW (+4 hp) and +7 Nm.
Note: Suits the E85 Z4 2.5i roadster with the 2.5L M54 (2003-2005 models). Installation by a professional is recommended.
