aFe Magnum FORCE Stage-1 Cold Air Intake - BMW 540i (E39) - 4.4L V8
The aFe Magnum FORCE Stage-1 replaces the factory airbox on the E39 BMW 540i with the 4.4L V8. A one-piece black powder-coated 16-gauge steel heat shield keeps warm engine air out and uses the factory mounting points, and a 3-angle adaptor smooths the air into the factory intake tract.
The 5-1/2 in (140mm) cone filter has an inverted top and uses Pro 5R oiled media. aFe's dyno testing shows up to +7.5 kW (+10 hp) and +19 Nm, with 62% more airflow than the factory intake.
Note: Suits the 1997-2003 E39 540i with the 4.4L V8. Installation by a professional is recommended.
