Fits select 2011-2015 BMW 135i, 335i, 335i xDrive, and X1 xDrive35i (I6-3.0L N55 engine).

Maximize the performance of your N55 engine with the aFe Power Momentum GT Pro 5R Cold Air Intake System. This system is engineered to provide a 26% increase in airflow over the factory intake, allowing your engine to breathe more efficiently for improved power and response. The heart of this system is the Pro 5R air filter, which uses five layers of progressively finer mesh cotton gauze oiled media to achieve a 98.6% efficiency rating while maintaining high flow rates even as the filter accumulates dust.

The system features a one-piece, CAD-designed housing roto-molded from heat-resistant cross-linked polyethylene (XLPE) to ensure a cool intake charge. A built-in sight window allows for quick filter inspections without disassembly, and an included urethane plug gives you the option to completely seal the air box. The dyno-tuned, roto-molded intake tube is designed for a precise fit and maximum velocity, securing to the engine with premium stainless steel clamps and a durable silicone coupling.
