Upgrade your S54-powered BMW Z4 M with the aFe Power MagnumFORCE Stage-1 cold air intake system.

The system includes a unique 3-angle adapter that optimizes air velocity and transitions smoothly into the MAF sensor tube, resulting in dyno-proven gains of up to 6 HP and 7 lbs./ft. of torque.

The included Pro 5R air filter features five layers of progressive cotton gauze media for maximum airflow and high filtration efficiency.
