aFe MagnumFORCE Stage-2 P5R Cold Air Intake BMW 3-Series E46 98-06 L6-2.2L/2.5L/2.8L/3.0L

The aFe Power Magnum FORCE Stage-2 Cold Air Intake System with Pro 5R Filter upgrades 1998-2006 BMW 3-Series E46 models equipped with 2.2L 2.5L 2.8L or 3.0L inline-six engines. It replaces the factory airbox with an open design large-diameter tubing and massive filter for dyno-tested gains of 11 horsepower and 13 foot-pounds of torque. A powder-coated heat shield seals hot engine air while channeling cooler outside air to improve combustion efficiency and throttle response.
