aFe Magnum Force BMW Intake Kit

aFe Magnum Force intakes are a performance replacement for your BMW's factory airbox and air intake system. These kits are fully engineered (not just put together to fit the space available) to maximize performance gains, with no check engine lights or similar issues. In-house injection molding machines allow the use of more complex intake tube designs which focus on increasing airflow and velocity.

aFe's innovative filter design is the next evolution of the lifetime, user-serviceable filter. Unlike the traditional oiled fabric filter which uses layers of cotton gauze, aFe filters are made from 6 staggered layers of precision woven cotton fabric of decreasing weave size, to maximize airflow while ensuring that contaminates are kept out of your expensive engine.

Full heat shielding keeps the incoming air separate from the rest of the hot engine compartment, meaning the intake charge is as dense as possible for maximum power. Several aFe kits also replace the factory mass air meter housing (sensor insert is transplanted), and employ a cover to fully enclose the intake compartment - view the spec sheets linked below for more information on specific kit contents.

Kits use existing mounting points, so there is no need to drill into or modify your car. Install yourself in less than an hour.
