aFe Momentum Pro Dry S Intake 51-82212 – BMW 320i / 328i / 428i (F30 / F32)

OVERVIEW

The aFe Power Momentum sealed intake system replaces the factory airbox on N20-powered BMW models with a fully enclosed, cold-air-fed setup. On aFe's dyno it produced 10 additional horsepower and 14 lbs. x ft. of torque, and it outflows the factory intake by 42%.

Air is drawn through the factory ram-air scoop into a one-piece, patent-pending black roto-molded airbox that keeps warm engine air away from the filter. Horizontal louvers moulded into the housing feed additional cold air to the element, and the box mounts in the factory locations for a straightforward installation.

Inside sits a 3-1/2" conical Pro DRY S filter built from three progressive layers of synthetic media. It requires no oil and cleans with soap and water. The intake tube is designed to maximise air velocity and was dyno tested and flow tested to balance power, throttle response and economy.
