aFe Momentum Pro 5R Stage 2 Intake – BMW 335i / 435i / M235i (F30 / F32 / F22, N55)

OVERVIEW

The aFe Power Momentum Stage-2 Si is a fully sealed cold air intake for the N55 turbocharged inline-six. In aFe testing it produced up to 11 horsepower and 15 lbs. x ft. of torque and outflows the factory intake by 37%.

The air filter sits inside a one-piece, patent-pending black roto-molded housing that keeps warm engine bay air away from the intake charge. A built-in clear sight window lets you inspect the filter without disassembling anything, and horizontal louvers molded into the housing feed additional cold air to the filter. A patent-pending filter-to-housing interface allows the largest possible filter while keeping installation simple.

The intake tube is CAD-designed to unleash the available horsepower and to fit the factory engine bay precisely. The kit ships complete with all necessary hardware.
