Product Description

The aFe Power 54-76313 Momentum GT Pro 5R Cold Air Intake System is a performance upgrade engineered for BMW vehicles equipped with the N55 3.0-liter turbo inline-6 engine, including 2011-2013 135i, 335i, 335i xDrive, and 2013-2015 X1 xDrive35i models. This intake replaces the restrictive factory air system with a one-piece sealed housing and oversized pre-oiled Pro 5R 5-layer cotton gauze air filter that maximizes cool air delivery to the engine for improved breathing, throttle response, and performance. The CAD-designed intake tube enhances airflow efficiency over stock, contributing to more responsive acceleration and engine character.

With measurable performance gains of approximately +12 HP and +14 lbs-ft of torque and up to ~26 % increased airflow over the stock intake, the 54-76313 delivers noticeable improvements in throttle response and overall performance. Installation is straightforward with a direct bolt-on design that requires no cutting or drilling, and the washable, reusable Pro 5R media helps reduce maintenance costs over time. This intake is not CARB exempt and therefore is not legal for sale or use in California and other states with similar emissions regulations. Fitment confirmed through 2015; coverage beyond 2015 is unconfirmed at time of listing.
